In this guide I explain how to remove and replace the LCD screen or inverter board in a Dell Inspiron 1525 laptop. Most likely this guide will work for many other Dell laptops. If it works for you, please mention the model number in comments after this post.
In order to remove the LCD screen and inverter board we’ll have to take apart the display assembly. Before you start, make sure the laptop is turned off and battery removed.
STEP 1.
There are six rubber screw covers on the screen bezel.
Remove all covers with a sharp object. You can blue covers on the screen bezel so they don’t get lost.
Now remove all six screws found under those covers.
STEP 2.
Start separating the screen bezel from the display cover. You may use a piece of plastic as case cracker.
Insert fingers under the bezel and carefully wiggle the bezel until it separates from the cover.
STEP 3.
Continue removing bezel on the top.
STEP 4.
On the bottom the bezel could be glued to the LCD screen with double sticky tape.
Carefully separate bezel from the screen.
STEP 5.
The screen bezel has been removed.
STEP 6.
Remove two screws securing the LCD screen assembly to the display hinges.
STEP 7.
Carefully separate the LCD screen assembly from the display cover and place it face down on the keyboard.
STEP 8.
Now you can access the back side of the LCD screen.
The inverter board mounted into the bracket on the LCD screen.
STEP 9.
Disconnect video cable from the LCD screen.
STEP 10.
Disconnect another video cable connector from the inverter board.
STEP 11.
The LCD screen assembly has been removed.
There are two mounting brackets on both side of the screen and inverter board on the bottom.
STEP 12.
Remove one screw securing the inverter board to the bracket.
STEP 13.
Turn the LCD screen assembly over and disconnect the backlight cable from the left side of the inverter.
STEP 14.
Now you can remove the inverter board and replace it with a new one if needed.
Here you can find new replacement inverters for Dell Inspiron 1525 laptops.
The best way to search for a replacement screen would be using Dell part number (0D196j in my case) or LCD model number (LP154W01 (TL)(F2) in my case).
If you are replacing just the screen, I would recommend buying exactly the same screen. When you use a compatible screen, you may run into a problem with screen brightness, it might non work properly.
If you want to use a compatible screen, I would suggest finding one with the inverter board attached.
Here you’ll find wide selection of replacement screens for Dell Inspiron 1525 laptops.
STEP 15.
After the LCD screen has been removed, you can remove left and right mounting brackets and transfer them to the new screen.
In order to remove the bracket, simply remove four screws on the side.
In one of my previous posts I explain how to replaced damaged keyboard on Dell Inspiron 1525 laptop.

[...] UPDATE: I just created a new guide for Dell Inspiron 1525 laptop. It explains how to remove and replace LCD screen and inverter board. [...]

Perfect instructions for the 1545!! I just replaced the screen in less than an hour. $80 for the new screen instead of $500 for a new system.
October 6th, 2010 at 7:01 pm
Check, good for a 1545. I ended up pulling the inverter even though I didn’t need to replace it, as it is very difficult to get the inverter connector back in with the inverter still connected to the computer. So go ahead pull the inverter just like the instruction advisew, even if you don’t need to replace this part.

Hi,
I’ve just found this site because yesterday I had a problem with my laptop and now I have to change the LCD screen. My laptop falled down and LCD is partially all (90%) broken but the bezel seems ok, so I just want to change de LCD screen. The computer works fine as I have it connected to the TV and all is ok.
My question is, I have a webcam on the screen cover (the bezel) , so I suppose there is a wire behind the screen where the wire comes up. Is there any difference when changing the screen? I want my webcam continue working after changing my LCD
Another question, is there any other way in order to know my part number or LCD model number without umounting the screen?
And the last one: I will try to buy the same LCD as I have. Do you recommend me buying the inverter board attached and change it too? The only part I can see of my partially broken screen I can see it well, like if the screen wasn’t broken.
Thanks a lot everyone and sorry for my english. I will follow this guide when changing the LCD
October 13th, 2010 at 8:35 am
Arnau,
Yep, sounds like you need a new LCD screen. If the laptop works fine with an external monitor (TV in your case), there is no other damage besides the LCD screen.
That’s right. There is a harness running from the webcam board to the motherboard. The webcam is a separate module and replacing the LCD screen should affect its functionality. When you remove the bezel, you’ll see the webcam module mounter above the LCD screen. Simply disconnect the webcam cable, replace the screen and connect the cable back into the webcam.
I don’t think so. The LCD part number and model number are printed on the label. If you want to be 100% sure that your new screen is compatible, I would suggest searching by the screen model number. It means you’ll have to open up the display assemble before ordering the screen.
It sounds like in your case the inverter board is not damaged but… when you replace LCD screen in a Dell laptop I recommend buying a new screen WITH the inverter board. They often sold in pairs.
Sometimes, when you replace just the screen, the brightness might now work properly. So far I’ve seen it happening only with Dell laptops. It will work but the screen will not be as bright as before. I think it’s some kind of compatibility issue between the backlight lamp and inverter. In Dell laptops the inverter must match the backlight lamp perfectly. Again, if you decide to buy a new screen, find one with the inverter board attached. If you cannot find one like that, make sure the new LCD screen model number 100% matches the original screen.

Hi Laptop Tech!
thank you very much for the very quick answer
I pending to recieve Dell’s official Tecnichal Support offer for changing the LCD, but they said me It will be too expensive. Also I’m pending to phone them again in order to know if they have this part number.
By the way, I’m very convinced about buying a new LCD (ebay maybe) and try to do it for myself.
So, thanks again and I promise I’ll say something after solving my problem
October 28th, 2010 at 6:48 pm
Those are great step-by-step instructions. I would never have known how to replace an inverter.
The only thing that was difficult was the screw in step 12 – I had to get vice grips to get that screw to turn.
My system was an Inspiron 1300, so just a little different, but I”m so glad I got it fixed. The part was only $8 on ebay! Thank you.
November 2nd, 2010 at 10:10 am
Hi Laptop Tech,
Thank you for this great guide. It is really appreciated.
Although I am dealing with the same laptop my problem is a little different.
I replaced this cracked Inspiron 1545 screen with an exact copy of the original and as a result the screen doesnt work anymore at all and neighter does the original.
Is it this bad that i might short circuit something and i need to replace the mobo ?
November 2nd, 2010 at 10:25 am
Ewald,
I cannot tell without testing the laptop.
1. Test your laptop with an external monitor. Can you get image on the external monitor?
2. Make sure the video cable plugged correctly. Maybe you accidentally disconnected it from the motherboard?
December 3rd, 2010 at 3:53 pm
Ok, my screen was going black, but you could see an image in the background very slightly. So we replaced the inverter in our Toshiba laptop and that didn’t work, was still having the same problem, so we order a display screen and replaced it, but I think I am missing a step, All I am getting is a white screen, Very bright though. I am thinking there is a trick to the video cable being plugged in, any ideas???
December 6th, 2010 at 9:33 am
I just replaced the screen a Dell Inspiron 1525 laptop because 1/3 of the screen had gone black. Your instruction were great!! The new screen shows a picture but it is very dark, the LT works fine with an external monitor. Would this be a loose connection, or bad inverter?
Thanks
December 8th, 2010 at 5:55 pm
Patrick,
How dark the picture is?
Is it dark like there is no backlight at all or it’s just not bright enough like before?
I assume it’s just not as bright as before, right? Usually it happens if you install a “wrong” screen. Dell laptops are very picky to new LCD screens.
If it’s not exactly the same model and version, it will work but will be not very bright.
When I have to replace LCD screen on a Dell laptop, I either buy EXACTLY the same model or if it’s a “compatible” Dell screen, I buy one with the inverter board installed.
December 8th, 2010 at 11:08 pm
vickie,
Make sure the video cable plugged correctly on the back of the LCD screen.
When you get a white screen, it means there is no data signal going to the LCD screen. Probably bad connection.
Try installing the original LCD back. Do you still get same dim image on the original screen?
If the original screen show image (even if it’s dim) but your new screen is completely white, it’s possible the new screen is defective OR not compatible with your laptop.

hi, i have a problem with my dell inspiron 1545. i got this from a guy that said it got steped on.so since i work on them for a living i decided to fix it for my daughters x-mas present. so i ordered a motherboard a screen , back cover , front trim. so i got it all put everything together and got it loaded everything with the external monitor but the screen was still dim to were u could barley see it with the lights on it but if u looked at it in the dark u couldnt see nothing. so i ordered the inverter thinking that was it that come put it in that wasnt it. ive tried a smaller screen we had in back that was stained that worked and it worked on it. but i tried to find a screen in town that was the same size so i could get it to work for her for xmas and when i found one it wont work and i cant get anyone to work now besides being dim again.could this be a keyboard issue cause i cant seem to get the brightness buttons with the func key to work ? or is it the cable that runs the screen from board to inverter to screen ? ive tried moving the cable around to see if there was a short but nothing happens ? i need help with this one cause im kind of puzzeled.
December 27th, 2010 at 9:42 pm
brad,
If the laptop worked with the stained screen but not with the new one, apparently the new screen is defective.
I don’t think so. If the screen has no backlight at all, it’s not related to the keyboard.
December 28th, 2010 at 12:43 pm
Hi thanks for the excellent guide…
I’ve hit a bit of a wall at point 12 though, non of my screwdrivers will remove the screw connecting the inverter to the screen, what should i be using!?
Thanks
January 5th, 2011 at 9:39 pm
No technical comment, just thanks for going to the trouble of supplying such detailed and competent advice. I hope you get some commercial benefit for your efforts, you certainly deserve to.
January 6th, 2011 at 9:47 am
Thanks for the great info. I need to replace the bottom cover on my daughter’s 1525 before she leaves to study abroad next week. Do I need to remove the LCD bezel or can I get away with disconnecting wires on the motherboard while the hinges are disconnected? In other words, do I need to completely disconnect the LCD before replacing the bottom? I’m worried that once I take off the bezel – I may need to replace it and I only have a week. Thanks so much.
January 10th, 2011 at 6:17 pm
HELLO PLEASE HELP ME I’M USING MY CELL I DON’T KNOW HOW ILL EVER FIND THIS WEBSITE AGAIN, MY COMPUTER SCREEN WENT BLACK AND I COULD SEE IT SLIGHTLY WITH THE LIGHTS OFF, I REPLACED THE INVERTER AND LCD SCREEN, MY UNCLE IS A COMPUTER WIZ AND HE CAN’T EVEN FIGURE IT OUT I DON’T KNOW WHAT TO DO PLEASE HELP CAN YOU EMAIL ME AT ALL
January 10th, 2011 at 8:17 pm
ashley,
Did you install brand new LCD screen and inverter?
If these two parts good, then you have either bad LCD cable or motherboard failure. It’s hard to troubleshoot this problem without spare parts.
January 10th, 2011 at 11:17 pm
Thank you, yes I replaced both and they were good, supposedly someone said Dell said its a bad BIN, I have no idea what that is or means, this has been on going for 6 months..its really sad and frustrating, when I turn my laptop on its black, only inthe pitch black with a flash light right up to the computer you can barely see it, I use an exteral monitor and that works fine, I replaced the lcd monitor and inverter, not I’m just lost, and I don’t really see any light here, I researched for 5months and still nothing, thank you for taking your time out to talk to me
February 3rd, 2011 at 5:44 pm
Hi there! I’m having a problem with my LCD screen. Each time I logged in my LCD turns into black. Our company technician taught me how diagnose it. He said, try connect to desktop LCD if it nothing happens then the LCD was the problem. So tried and it works coz I don’t have any problem with my computer aside from that.
And now, I discovered your website showing the technic on how to replace LCD ourselves. This help us a lot in saving cost to labor and it serves as an additional knowledge us knowing our personal computer.
Yyou have mentioned here that it’s not advisable to use compatible LCD because, we might end up in a not satisfactory result. Lucky, I’ve found this website of yours coz I’m planning to buy already a compatible replacement. Now, since I know already what to do, I’ll follow your advise.
I might ask you in the future if I encountered some problem during the replacement of my LCD.
Again, thank you for your wonderful and educational website. Keep up the good work and GOD bless.
February 9th, 2011 at 8:10 pm
I dropped my Dell 1525 from about 2 feet on the tile floor. I thought Hard drive went bad, but connecting to desktop monitor confirmed that it was LCD that went bad. After finding the instructions on this site, I took it apart and ordered exact Dell part (new) for LCD that includes inverter. I was shocked to see there is no difference with the new LCD. I do not see any light in the LCD. I correctly inserted data cable and inverter cable. I checked to make sure these two cables are tight and secure. I read on this site and several others that replacing LCD should take care of it but what else is going on with my laptop? Any lose connections inside the laptop? Is it something I can take it apart? or any other tests I could do? I really appreciate your time and help with any advice you could give.
February 11th, 2011 at 2:23 pm
Alot of the above mentioned problems stem from the back light (yes there is a CCFL) back light in your screen at the bottom. The CCFL is nothing more then a very long and small florecent light. Yes you can change them but its not a job for the impatient or light hearted as it takes alot of time and patience to do one
February 12th, 2011 at 6:52 pm
Hi,
I have fixed computers in the past, But this one is different . LOL This is Dell Inspiron 1545 Laptop with an LED screen.
I checked the lid switch- OK
I check connection to motherboard- Ok
Plugged the laptop into monitor- Ok
Old screen doesn’t work and did when cracked before
This doesn’t have any kind of inverter that I can see. I assume it gets it’s power directly from the motherboard. Like I said this is not a CCFL.
I cannot find ANYTHING to help me describe if it is integrated (Inverter) into the board.
I have never seen so many complaints about this in my life. lol
Thanks for your help
March 9th, 2011 at 6:46 pm
Guys, I’m in a very similar spot and I actually suspect I know where the physical problems lies, I just dont know how to proceed. I’ve changed out LCD screens before and never had a problem, but this one is driving me nuts. My daughter dropped her Dell 1525 Laptop, smashing the front bezel and hinges and cover. The system still powers up and the screen is not cracked.
I’ve swapped in new hinges, cover. bezel, etc…however there is one small black wire that reaches into the screen cover along the left hinge, but isnt actually connected to anything. Its not one of the 4 wires that feeds along the monitor frame, and is only maybe 2″ long, and I have no clue as to what its supposed to tie into. Suggestions?
Thanks in advance!
March 10th, 2011 at 11:47 am
Chuck Brown,
Looking at the Dell 1525 cover right now.
There is a black cable (about 2″ long) which is soldered to the green board located to the right from the left hinge. Looks like this is one of the antenna cables (Wi-Fi antenna?). Most likely it broke of off the antenna board when your daughter dropped the laptop.
March 13th, 2011 at 8:23 pm
Hey guys, I have a similar problem with my laptop screen. On start-up, it flickers and then goes dim. No black-light. External monitor works fine. I replaced the inverter and there was no change. The thing is the screen randomly turns on and works perfectly. Since its doing this, I dont think there is anything wrong with the screen but maybe some sort of power problem . Yet how can it just randomly start working by itself? Any ideas?
March 13th, 2011 at 9:17 pm
Dave,
Probably you have bad backlight lamp inside the screen.
Here’s something to try. When you use the laptop, turn the LCD screen brightness about 50% down and use it this way. Will it fail with reduced brightness? If not, most likely this is backlight lamp failure. Replace the screen.
March 18th, 2011 at 12:47 am
I have a 1525, I have a dark screen, seems like no back light, the screen is very dim. I replaced inverter but to no avail, do you think that it is the lamp or maybe a cable issue? Where should i go from here?
March 18th, 2011 at 12:09 pm
Steve,
If you replaced the inverter board but the problem is still there, most likely this is failed backlight lamp. The next step would be replacing the LCD screen because it’s very hard to replace just the backlight.
Here’s an advise. When you buy a new LCD screen, buy one with inverter board attached. This will guaranty that your inverter matches the screen.
If you but just the screen, there is no guaranty your original inverter will match and in this case the brightness will not work properly. It will work but will not be as bright as before. Buy a combo.
There is chance that you have failed video cable or even bad motherboard, but this is not very common. Most likely it’s just a bad lamp.
April 4th, 2011 at 6:40 am
hi just wondered if a screen from any similar dell laptop will fit an inspiron 6400?
May 11th, 2011 at 6:12 am
My daughter dropped her Dell Inspiron 1545. Screen was cracked, showed typical white with bleeding black spreading from corner of impact. Screen was a Chungwa CLAA156WA11.
Computer works fine connected to external monitor.
I ordered and installed a replacement screen (Samsung LTN156AT02). Screen is completely black. Still works fine with ext montior.
Old screen and new screen only have one connector (video) to screen. No inverter, or backlight connections. Is this correct?
Any suggestions? Thank you for any help or hints.
Bill
May 12th, 2011 at 12:26 pm
Bill,
Is the new screen compatible with your Dell Inspiron 1545 laptop?
Try installing the original cracked LCD screen back into the laptop. Does it light up?
If the old screen lights up but the new one doesn’t have any light, the new screen either not compatible OR defective.
I cannot tell without testing the laptop.
Probably your laptop has LED-backlit LCD screen which doesn’t have backlight lamp and has only one connector for the video cable. Yes, it sounds rights.
May 15th, 2011 at 2:01 pm
Thanks for all the great info you provided. I have a Inspiron 1525 with 1280X800 screen. I see there is a WUXGA screen available for this model. Can I just swap it out or there is more involved than just swapping screens?
Thanks.
May 15th, 2011 at 3:05 pm
John,
I believe in this laptop just swapping screens will work. If not, you’ll have to find a WUXGA compatible video cable.
Again, I think just swapping screen is fine.
May 15th, 2011 at 8:15 pm
Great! Thanks again for your efforts. It’s greatly appreciated.
May 25th, 2011 at 2:23 am
Hi, I have a quite tricky issue, the nobok felt down, got a tiny crank on the plastik cover. Actually the notebook an display works, just the corner ( left botton ) gets quickly extrem hot, that even the color changes. Andy idea ?
May 28th, 2011 at 2:28 pm
@ Robert,
Hard to tell what’s going on.
Listen for the cooling fan. Does it work at all?
It’s possible the cooling fan got damaged and doesn’t work anymore. Just a guess.
May 31st, 2011 at 10:15 pm
There some sort of firmware hash on the panel. so far, every panel i have had with a compatible inverter works. but the exact panel that didn’t does not.
well dell loses my future business.
November 3rd, 2011 at 8:27 pm
My lcd screen is warm hmmmm kinda hot in the inverter area of my lenovo y510… Is there an issue with the inverter or will the inverter get heated like that always?
November 4th, 2011 at 7:31 am
@ lenovoy510,
Usually inverters get warm while working but not very hot.
November 5th, 2011 at 4:49 pm
Hello,
Thanks for the easy to follow instructions. When we put the new screen in our inspiron 1525, the backlight works fine but there is no image displayed. At first, the screen is a little white but then it turns black (still with backlight). We have confirmed that the computer works fine by plugging into an external monitor. I also confirmed that the signal cable is plugged in to the system board and at the top of the monitor. Any ideas? Thanks
PS: the old monitor needed to be replaced because it was cracked and the image was scrambled (dropped)
December 10th, 2011 at 5:55 am
My inverter area is also warm … is it normal…. can we really distinguish b/w warm and real hot….
December 11th, 2011 at 12:10 am
@ lenovo y510,
If you touch the inverter area with your finger and it’s not uncomfortably hot, probably it’s OK.
December 13th, 2011 at 1:56 am
Hi I need some advice… i have a dell inspiron 1300 with 3 colour lines down the screen which is annoying… i also have a dell inspiron 1501 with a dead motherboard( screen was ok)… can i use the screen from the 1501 in the 1300? will the inverter and connections be the same? also will the main computer processor work in the 1300 also…im trying to salvage all the good bits into one computer..
thanks
December 13th, 2011 at 7:05 am
Like others, the screen on my 1525 went almost completely black – the only way to see the screen is to shine a very bright light on it (and even doing that, it’s almost impossible to see the image, but it’s there and there are moments when I can see the laptop screen when connecting an external monitor. It’s a bit maddening because it looks as if the laptop screen is going to stay lit, but then it goes out.)
I’m waiting for the “new” inverter board (can only find a used one).
Decided to do a dry run dissembling the screen so that I have a better hands on idea of what this involves (and for deciding whether or not I’m completely up to the task).
To clarify a couple of things……
In addition to the connections being in place, both the video cable and the inverter board are FIRMLY taped down – I almost hesitate to pull the tape off especially on the video cable connection to the screen because I’m concerned about damaging other components. Less concern with the inverter board because the tape is across the bad inverter and the frame.
Is it possible to replace the inverter board without removing the video cable from the screen and if not do you have any suggests – besides being very careful! – for removing the tape from the video cable connection to the screen?
Also is it necessary to re-tape the video cable and the “new” inverter after replacing the inverter?
Thanks for your help.
December 14th, 2011 at 2:03 pm
@ John Richards,
Cannot tell without trying. It looks like both laptops have 15.4″ screens. If both screens have the same resolution it might work.
When you transfer the screen, make sure to transfer it with the inverter.
Connectors for the video cable should be the same on both screens.
December 14th, 2011 at 2:22 pm
@ Patti,
The inverter board secured in the metal bracket attached to the bottom of the screen. It will be hard to remove the inverter without disconnecting the video cable but possible. Depends on your tech skills.
Before you remove the old inverter, I would suggest testing the “new” inverter. Simply disconnected the old one, plug in the new one and see if the problem fixed. If not, most likely this is backlight failure. If that’s the case, you’ll have to replace the screen.
Yes, I would do it to make sure the cable is secure. You can use regular sticky tape.
December 17th, 2011 at 7:24 pm
Thank you for answering my questions in post #49.
I was able to buy an identical inverter board, unfortunately it did not repair the almost black screen (I can seen a faint image if I hold a bright light up to it, and sometimes when I connect the external monitor, the laptop display comes on but only for a few seconds). Also with the “new” inverter, when Windows loads, the screen – for a moment – looks almost green, which is a first.
I’ve been connected to an external monitor without problems but I really want to make the laptop whole again since the external monitor is only good at home.
Before I spend $100 on a “new” screen (the only ones I’m finding are used) is there anyone for me to be sure that the issue isn’t with motherboard – my concern is that the screen problem is the start of the motherboard going south- is that possible?
I have minor issues with the laptop (the battery no longer fully charges, so I stick to the AC adapter) and I want to replace the keyboard mostly for cosmetic reasons, but it works. Otherwise, the laptop works fine (except for the black screen).
Could the screen being almost black have something to do with another part other than the back light?
And this may be an idiotic (!?) question but does the video card have anything to do with this type of problem or is it that once the screen losses brightness, the problem can usually be narrowed down to either the inverter and/or the backlight.
Thanks again – I really appreciate it – Patti
December 22nd, 2011 at 5:23 am
Hi,
when screen brightness is lowered (30%) the inverter area is less warm than 100% brightness… is this normal….. i think i am unnecessarily paranoid…. i think its normal// what say?
December 23rd, 2011 at 2:43 pm
@ Patti,
Unfortunately it’s hard to troubleshoot backlight issues without spare parts.
I cannot if you backlight issue is related to the motherboard failure. The only way to find out is testing the laptop with another screen.
If you decide to buy a new replacement screen, make sure it comes with the inverter. In Dell laptops it’s important to match the inverter with the screen. If they do not match, the brightness will work but not properly.
This could be:
1. Bad inverter (which you already replaced.
2. Bad backlight lamp inside the screen.
3. Bad video cable.
4. Bad connection between the video cable and motherboard.
5. Motherboard failure.
December 23rd, 2011 at 6:17 pm
@ lenovo y510,
How hot is it? If you touch the inverter area with the back of your fingers and it’s comfortably warm, probably it’s OK.
January 2nd, 2012 at 9:23 am
I ordered a replacement LCD Screen for my Dell 1525 Lap Top and when i got it there is no bracket on the new one at teh bottom that should hold the inverter and the old onew won’t fit on the new one also there is no top brackets where i need to screw into the lid to hold it in place. What do I do?? Thanks and great site…
January 2nd, 2012 at 1:13 pm
@ Marty,
Install the new LCD screen and glue the inverter under the screen with double sticky tape. It should be enough to secure the inverter. I’ve done it myself before a few times.
January 7th, 2012 at 9:22 pm
Hi, I replaced a screen on a similar laptop about a week ago. My problem is with the piece of tape that holds the video cable to the screen. The cable itself doesn’t seem to have any sort of latch of any kind. And the tape doesn’t want to hold very well. After a while the cable works itself out. Is there a suitable substitute that I can use?
Thanks for any ideas!
January 8th, 2012 at 11:10 am
@ Avery,
A regular clear Scotch tape should work just fine. Using it all the time.
January 25th, 2012 at 12:38 am
i bought a dell inspiron 1420 with a faulty LCD but after replacement the brightness is so poor even if adjusted fully.what could be the problem
January 25th, 2012 at 12:19 pm
@ Collins Alum,
Did you replace just the screen without replacing the inverter board? It’s possible your original inverter doesn’t match the screen. That’s why the brightness doesn’t work properly.
What happens if you adjust brightness using the keyboard keys? Does it go up and down without any pattern? If yes, probably you’ll have to find the correct inverter which matches your screen.
February 7th, 2012 at 7:03 pm
Hey Laptop tech,
I just dropped my laptop & a white wire just snapped between the screen next to the blue & black/gray wire on the left. Everything is still working fine. What is this white cable used for?
Dell Inspiron1525 owner
February 8th, 2012 at 6:53 pm
@ Nisha,
I think you are talking about wireless card antenna cable.
Probably the wireless card still works because it has another antenna cable connected.
February 14th, 2012 at 9:40 am
Hi,
I am in the process of replacing the screen on a Dell Inspiron 1545 (CCFL) which had stopped working (dark). Before I commit to the expense of buying a new screen I purchased a CCFL tube with wires and plugged into the inverter to confirm, it came on as soon as I powered up……so confident a new screen is required.
Having removed (and scrapped) the old screen I tried a few days later to repeat the test with the screen removed but the CCFL test lamp now fails to illuminate when connected. The pc continues to work when connected to an external screen.
Is it smart enough to know there is no screen connected and therefore no need to fire up the inverter or do I have to look elsewhere as to why this is the case ?

@ Colin,
Did you connect the backlight lamp without old LCD screen connected to the laptop?
It’s possible your laptop requires the LCD screen to be installed in order to light up the backlight lamp. Probably there is some kind of signal going from the screen to the motherboard.

I got an inverter for $8.00, followed your instructions, and it’s like I have a brand new screen.
Thanks for this!

Hi Ken,
I have the same problem, The screen went dark. The LCD is still working as i can see it but very dimly. I think the inverter is busted and it won’t power up the light. Could you please tell me where you found the inverter for $8.
Thanks,
Tamas
