This guide will help you to remove the LCD screen and inverter board from a Sony Vaio VGN-SZ645 laptop display. I think these instructions will work for many other Sony Vaio models.
Do not forget to remove the battery before you start.
Related articles: In my previous post you’ll find how to remove the keyboard and replace the hard drive.
OK, let’s take apart the display panel.
STEP 1.
Using a sharp object (or small screwdriver) remove four rubber plugs. There is on plug in each corner of the display bezel.
STEP 2.
Remove four screws found under rubber plugs.
STEP 3.
Start removing the screen bezel as it shown on the picture below.
STEP 4.
Continue removing the bezel. Be careful, do not apply to much force because the the screen bezel is made of thin plastic.
STEP 5.
Remove the screen bezel.
STEP 6.
In order to replace the screen inverter you don’t have to disassemble the laptop any further. Simply unplug two cables from both sides of the inverter board. I pointed these cables with two red arrows. Carefully remove the inverter board and replace it with a new one.
STEP 7.
Here’s how you can replace the LCD screen.
Carefully remove the LCD screen from the cover and place it face down on the keyboard.
STEP 8.
In order to remove the LCD screen you’ll have to:
1. Unplug the video cable from the connector on the back of the LCD screen.
2. Unpug the LCD backlight cable from the right side of the inverter board.
Now you can replace the LCD screen with a new one if needed. Search for the replacement LCD screen here.

Sony VGN-SZ645 has a problem with the LEFT side touch pad button.
Sometimes it works….sometimes not.
Can the contact (s) get worn out or dirty??
Any suggestions for repair or replacement??
Thank you!

bobz,
First of all, test your laptop with an external monitor. Make sure the external video works fine. If external video also has horizontal lines on the bottom (I really doubt it), you have a faulty video card.
If external video works fine, your problem could be related to one of the following:
1. Bad connection between the video cable and motherboard or LCD screen. Try reseating connectors.
2. Bad video cable. Here’s what you can try. Disassemble the laptop display and try moving the video cable while the laptop is turned on. If moving the cable affects video on the screen, it could be bad cable. Replace the cable.
3. If moving the cable doesn’t affect video on the screen and all lines still there, probably you have a faulty LCD screen. Replace the screen.

HI, Thank you very much for this demo. This was very helpful. I ordered the screen for $85.00 including shipping and replaced it myself. Sony quoted $450 to $600 range for this.
thank you very much.

I have an VAIO VGN AR590CE. Upon start up there is one Long, and 2 short beeps. The screen is completely black and I cannot see anything. I know the system still works because i can hear the start up sounds. The windows Chime and the Logged in sound. SONY will not help because it is out of warranty. Any thoughts other than bringing it in to a pro?
Many thanks.

David,
I think there is no inverter because it’s a LED backlight LCD screen.
You cannot tell what is causing the problem without testing the laptop with another screen.

Hi, I have exactly the same problem as Enzo95 posted, SZ2XP/C dim lit screen, I suspect magnetic lid but I have no idea what to do next. Picture is very dim but visible right from the start. There is no inverter on this model. Please let me know what to do…

Hello all,
I do nit really have the model above (VGN A197 XP) but your tip on where to find the screws for the display really helped. Just replaced the right hinge for the LCD.. It all worked out!

Hi,
I have 2 Vaio notebooks, SZ2XP en SZ1XP, carbon fibre models with razor thin LCD.
Recently, backlight on SZ2XP suddenly died, when connected to an external monitor everything works fine and if you look at the screen closely with a lamp, everything is there.
Following your instructions – razor thin lcd model is a bit different though, does not have a inverter – I opened up both notebooks and swapped the LCD screens. The LCD which was not working on SZ2XP worked fine on SZ1XP, the fine working SZ1XP LCD put on SZ2XP had the same backlight issue. Swapping the LCD cables did not make any difference, bringing me to the conclusion that the SZ2XP LCD and LCD cable are OK but something might be wrong with the motherboard.
However, after assembling the working SZ1XP back, I turned the notebook on and guess what it had the same backlilght issue,ending up with two notebooks having the same problem.
After cooling my head down and doing some internet search I suspect that I might have an issue with the lid close switch causing backlight to stay off but I can not find the switch around the hinges. Do you have any idea where lid switch would be and if my assumption could be correct?
Sorry for the long story,I just wanted to make sure I did not forget anything. Thanks for your time!

dexxy boy,
First of all, you’ll have to test your laptop with an external monitor attached to the VGA port.
If you can get image on the external monitor, most likely your problem is related to the LCD screen or cable.
If there is no image on both, the internal LCD and external monitors, most likely the problem is not related to the LCD screen or cable. Something else is wrong. Could be bad memory module.
Test your laptop with an external monitor and find out if you can see the image. On some laptops you have to force the video output from the internal mode to the external mode using a shortcut on the keyboard. Something like Fn key and F* key.

I have a vaio sz420n. the display has a white horizontal band approximately two inches thick on the bottom side of the display. this band sometimes clears up, wbut there is faint banding and or a thin white horizontal line about half an inch from the bottom. Should i be changing the display or simply the video cable which is ttached to the lcd display. Is it the display at all or possibly a bad driver software?
I look forward to your kind response.
Thanks and Regards

I am trying to repair a sony SZ645. It has no picture but works with an external monitor. I pulle the bezel off and the screen but your photos show a video cable taped to the back of the screen. Mine does not have this. I have had several people tell me this screen has no inverter and they have tried to sell me a bulb. There is a small board taped to the bottom of the screen and I am assuming this is an inverter. Can you confirm this unit is a LCD and not a LED screen?

LimLim,
I cannot answer your question without looking at the laptop. It’s necessary to remove the screen bezel to find out what’s going on. Maybe screws on one left side of the screen got loose and the entire screen moved to the right. Just a guess.
