In this guide I will remove the LCD screen and FL inverter board from an Acer Aspire 3620. The guide will work for other Acer Aspire models. If it works for your, please mention the model number in the comments below.
You’ll find my first disassembly guide for the same Acer Aspire 3620 in the previous post where I explained how to remove the motherboard and clean the cooling module.
Let’s start taking it apart.
Step 1.
You’ll find four rubber plugs in four corners of the LCD screen bezel. Remove these plugs with a sharp object and glue them somewhere on the bezel so they don’t get lost. Remove four screws hidden under the rubber plugs.
Step 2.
Start separating the screen bezel with your fingers. I found it’s easier to separate the bezel if you start from the top.
Continue separating the bezel. Be careful with the display latch, it has to stay attached to the screen cover.
Finally, remove the LCD screen bezel.
Step 3.
You’ll find the screen inverter board also known as FL inverter mounted below the LCD screen. Remove two screws securing the inverter board.
Step 4.
In order to remove the inverter board, you’ll have to unplug two cables.
The black cable on the left side is connected to the motherboard. It supplyis power to the inverter board from the motherboard.
The cable one the righ side is connected to the backlight lamp inside the LCD screen.
Now you can replace the inverter board with a new one if needed.
I’m not going to remove the LCD screen because I’m taking it apart just for this guide.
Step 5.
Remove two screws securing the LCD screen brackets to the hinges.
Now you can separate the LCD screen assembly from the cover and access the back side of the screen.
In order to remove the LCD screen assembly you’ll have to unplug the video cable first.
After the video cable is unplugged, you can remove the LCD screen assembly (screen and mounting brackets).
If you are replacing the screen with a new one, you’ll have to transfer mounting brackets to the new screen. You can find a new screen for your Acer Asprie 3620 (and any other Acer laptop) here.

ramalingam,
I will as soon as I get one for repair.
By the way, the display disassembly steps will be very similar for most laptops.
1. Remove rubbers seals found on the display bezel.
2. Remove screws found under the rubbers seals.
3. Remove the bezel and you are inside.

is it relitavley easy to replace the screen on a 6920 g? and is there much you can break when you take the cover off?

jon,
I’m not familiar with that model but taking apart the display panel is very similar for most laptops.
Not really. Just be gentle with the video cable connectors, do not touch the controller board (logic board) on the back of the LCD screen, be gentle with the inverter board. Other than that, it’s relatively easy to replace the screen.

I hate my Acer. But I do need a little help, if you don’t mind! The backlight sometimes works, sometimes not. I’m guessing there is a poor connection. Hoping it’s not a solder situation. I have a 3680 Aspire, which has two additional hard plugs at the top of the bezel, in between the screen latches.
What should I be looking for? How do I get those additional plugs out? I’m not so concerned about scratching the surface, Just don’t want to kill the beast. I’m kind of desperate, as I teach my kids through cyber school, and my main system, an HP laptop has to go in for a motherboard recall. UGH!
Thank you SO MUCH for any help you can provide!

This entry was helpful. Would you take a few moments to look at the URL posted below.
It includes pics from my Acer Aspire 5100-301. It has now developed an annoying sporadic green or blue strip on the far right side of the screen.
Is this an inverter issue or just a simple screen replacement?
See here and here

AG,
This is a problem with the LCD screen. You’ll need a new screen or use it as is. The problem is NOT related to the inverter. I’m sure 100%.

Benny,
1. Go to the device manager, right-click on the wireless adapter and uninstall it. Now restart the laptop and let it detect the wireless card again.
2. Try reinstalling the device driver. You can download the wireless card driver from the manufacturer’s web site.

Have a acer aspire 6920G and have now two screens that were shipped to me, The number on the old screen ( creacked) is the same as the one on the the two new screens. Take old one out and put new one in and I only get vertical lines on it back light comes on. Then i insert old cracked screen and it works fine- except for the crack. What am i doing wrong is there a certain install procedure for this laptop.

Thanks for the great detailed photo.
The left side of my Acer 3620 LCD wil sometimes went dark, while the right side is fine. This usually last a few days.
The darkening appears to be analog rather than digital. The edge between the dark side and the normal side is nicely feathered and no pixelated.
Does it sound like an inverter issue to you? Thanks again for your help.

thanks for the instructions on changing out the LCD. I got the screen changed out, but still no picture. I have an external monitor hooked and have tried sharing the desktop to both displays with no luck. I can see the laptop display flicker when I change settings but no picture. Are there any hardware updates I should do when changing out the lcd? Any other suggestions would be greatly appreciated. Thanks

Joey,
Why did you replace the screen? Maybe your problem wasn’t related to the screen at all?
June 29th, 2009 at 4:58 pm
my Acer 3620 works great. my screen has broken off at the hinges. The screen and the hinges are both broken. The only parts that have remained intact are the black hinge brackets attached to the laptop body above the speakers.
Where can I find the hinges? I know I can find the screens online but I need the hinges or better yet the LCD casing and the hinges, the actual screen still works great but it is completely detached except for wires from the laptop

exp,
Try here.
I see both hinges for an Acer 3620 laptop for $20.

How did you get the bezel off your acer 6920g ? I’ve removed ALL the obvious screws on the front but it won’t budge – am i missing something ?
July 11th, 2009 at 12:34 pm
Hi,
I have an Aspire 2930 which I spilt water on the other day (big whoops!!) since then the illuminated logo on the lid doesnt turn off in sleep mode, I have to turn it off all together for it to go off. is there a cable I can dissconnect so it stop draining my battery?
Thanks for the info above, it’s help me get so far.
July 13th, 2009 at 2:59 pm
hi, i just was wondering what happen if i remove the LCD but i dont replace it, just leave the laptop without the lcd screen?
July 18th, 2009 at 1:29 pm
Hi, I have an eMachines d620 laptop and the screen was cracked so I took it apart according to your pictures and instructions. It looks basically the same inside. Anyway, I took it apart as a practice to make sure I could do it. I am still waiting on a screen. But when I put it back together with the cracked screen, all I get is a black screen. It doesn’t seem to be powering on. I put everything back together and it wasn’t working so I took it apart and checked to make sure everything was connected properly. It seemed to be, but still no power. Can you help? Thanks.
July 18th, 2009 at 11:43 pm
Big D,
I assume the laptop was powering up before you took it apart, correct?
Take a look inside the connector on the motherboard. Maybe you accidentally bent pins inside the connector while connecting the cable?
You said there is no power. Does it mean the laptop is completely dead?
July 19th, 2009 at 12:48 am
Dajo89,
If there is nothing wrong with the laptop, it should start just fine with an external monitor attached to the VGA port.
July 23rd, 2009 at 4:34 am
To Steve
Did you get the brackets off of you acer 6920g? I have the same problem, can`t reach the bottom screws.
July 31st, 2009 at 6:08 pm
hello, my acer 3623wxci periodically displays this message:
hardware malfunction, call hardware vender for support
nmi: parity check/memory parity error
system halted
then the laptop freezes, the only way i can reboot is to turn off the power. it still works fine after i turn the power back on.
also what is the biggest hard drive that can be installed ?, right now i only have 40 gb . can the hard drive be purchased anywhere or must it come from acer ?
ps: great website

Just a quick note to let you know how much I appreciate your site and the time you put into helping. Many thanks.

My Acer extenza 5420 has a white border around the screen
does it call for a screen or inverter replacement.
September 10th, 2009 at 9:00 pm
tallboy,
If you can see the screen (or part of the screen) and it’s bright, your problem is not related to the inverter.

Hi, my Acer Aspire 3620 Notebook failed to work after my nephew unintentionally plugged into a faulty AC power socket . Is there such a thing as a fuse in the Aspire 3620 Notebook that could have blown??
Cos’ if that’s the case, then I can rely on your instructions at http://www.insidemylaptop.com/clean-cooling-module-acer-aspire-3620/ to open up the notebook to replace the fuse?
Thanks with appreciation
Francis from Malaysia
September 21st, 2009 at 9:14 am
Francis,
Yes, it’s possible but I cannot pint you to the fuse. In most laptops the fuse is located somewhere close to the DC power jack.
You’ll have to remove the motherboard, find the fuse and test it with a multimeter. If the fuse is open, solder a new one.
Yes you can. My guide will help you to remove the motherboard but you’ll have to search for the fuse on your own. Again, it’s located somewhere close to the DC jack.

Hi I feel really terrible, one month back I bought this Acer Aspire 6920g everything seem so perfect until one day I noticed that cracks started showing up both on the right and left hinges. Now my question is what should I do? Should I just ignore it or the situation might get worse. Need help searched a lot of forum and majority of the users complained about the same problem and all of them Acer users
October 8th, 2009 at 7:17 am
Moon,
Is it still under warranty? Contact Acer and explain what’s going on. Maybe they will fix it under warranty.
October 28th, 2009 at 6:55 am
Hey,
i have an acer aspire 3050 . My Screen Cracked and I got the same computer from a guy on e bay .
so i could replace it . but i was wondering what tools i need.
is it easy to replace ? just UNSCREW and screw back ?. or is there more than that. ?
if you could e mail me at soliderjay @ yahoo.com
October 28th, 2009 at 10:02 am
Josh,
You need a small philips screwdriver.
It depends.
If you want to replace just the LCD screen, you’ll have to disassembly both display panels and remove screens.
If you transferring the entire display panel (LCD, cable, inverter, plastic covers…) it’s not necessary to take apart the display panel.
October 28th, 2009 at 11:05 am
HEY ,Thanks
OK i know how TO REPLACE IT NOW.
just one more question
A GUY ON EBAY IS SELLING A ACER ASPIRE 3050 JUST LIKE MINE HE SAYS THAT HIS SCREEN GIVES NO IMAGE
SO HE JUST TOOK HIS HARD DRIVE OUT AND IS SELLING IT.
DO YOU THINK THAT THE SCREEN IS NO GOOD IN IT?
OR SHOULD I BUY IT AND SWAP THEM OUT MINE IS GREAT AS FAR AS THE INVERTER
AND BACK LIGHT
ITS JUST CRACKED .
DO YOU THINK HIS SCREEN WOULD WORK OR SHOULD I SAVE MY 60 BUCKS.
HE’S WANTING ME TO BUY IT NOW.
I DONT KNOW WHAT TO DO?
October 28th, 2009 at 11:16 am
Josh,
Be careful, the screen could be in bad condition or not working at all.
Why wouldn’t you buy a brand new LCD screen with warranty? They are pretty cheap on eBay. Is there any reason to buy another used Acer 3050?
What if it’s scratched, has dead pixels, crappy image. Are you ready for that?
October 28th, 2009 at 1:13 pm
HEY ,
THE REASON FOR JUST NOT BUYING A NEW SCREEN IS
IT COST 71 BUCKS PLUS SHIPPING CHEAPEST ON E BAY
AND MY LIMIT WAS 50 BUCKS TO START BUT HE WANTED 50 AND 9 FOR SHIPPING
SO 60 BUCKS STILL CHEAPER AND I GET THE LAPTOP EVERYTHING IN IT BUT THE HARD DRIVE.
I HOPE THERE IS NOTHING WRONG WITH IT.THERE IS A 3 DAY MONEY BACK GUA.
WOULD IT BE POSSIBLE IF I COULD I M YOU OR CALL YOU ONCE IT GETS HERE.
IF I HAD ANY QUESTIONS.
WITCH IS NOT BAD IF EVERYTHING WORKS IN IT . AND I COULD USE THE MEMORY IN IT
TO ADD TO MY COMPUTER. I THINK THAT I COULD DO THAT.?
I DON’T KNOW HOW . BUT MY COMPUTER COULD DIFF USE MORE MEMORY.
DO YOU HAVE A STEP BY STEP GUIDE TO PUTTING ONE MEMORY STICK,INTO ANOTHER SAME PC?
THANK YOU FOR YOUR TIME AND ANSWERING MY QUESTIONS.
IT REALLY HELPS ME OUT AND IM LEARNING I AM PURSING A CAREER IN COMP TECH
ONCE AGAIN THANK YOU.
November 2nd, 2009 at 9:26 pm
thanks for all your help. it worked great.
i do want to ask tho . he had 1gb memory.
i have 2 ,,512mb,,,can i take out 1 ,,512,,and switch it with 1gb ?
November 2nd, 2009 at 9:39 pm
Josh,
Is it for an Acer Aspire 3620? Yes, you can.
Aspire 3620 laptop can take 2GB memory total. You can install up to 1GB memory module into each slot. You can use different size modules, for example 512MB in one slot and 1GB in the second slot.

Still haven’t seen how to remove the bezel on an Acer 6920. I have a screen but can’t get the bezel off. Some posts mentioned removing the on/off bezel but didn’t say how to do that either. Any help is greatly appreciated!

January 9th, 2010 at 9:56 am
I left this message a while ago but I never got the screen I ordered. My question is, If I have a EMD620-5748 can I purchase a screen said to fit a EMD620-5777???? They are the same size (14.1″) but I was curious if they have to be EXACTLY for this computer? Thanks.

February 11th, 2010 at 5:21 pm
I have the need to seperate the lcd diplay / top of a netbook from the base of a netbook. ( so I can mount the display on the wall and have the computer a few feet away. Anyone know if thats doable it is next to impossible to find 10-12 inch lcd monitors with vga inputs
February 12th, 2010 at 7:03 pm
mrmike,
I don’t think that you can do it. The video cable is shore and I doubt that you can extend it.
