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.

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.

Hi, thanks for the instructions, they’re really useful. I have recently cracked my VGN-SZ4XWN screen and would like to replace it. Do you have any recommendations on where to purchase a replacement?
The model number is LTD133EXBY and most companies seems to say it has been discontinued. There are a few screen floating around on eBay but some of them quote a different resolution (not 1280×800). Is this the best place to get one?
Thanks!

Hi, I have a Sony Vaio VGN-CR220E the screen turn white when I turn on the laptop, only works if I press the top of the screen (the border). When I release the screen many white points appears and go intesifying until turn white all screen. In addition looks like in standby mode because if I move the mouse or press the keyboard nothing happend.
The notebook have 1yr and 1 month and doesn’t have warranty.

Nancy,
The LCD screen removal and replacement procedure is very similar for most laptops.
1. Power off the laptop.
2. Remove the screen bezel.
3. Unplug cable from the LCD and inverter.
4. Unscrew the LCD from the hinges/brackets.
5. Replace the LCD with a new one.
I don’t know, it depends on your technical skills.

Hi, my little brother recently dropped his laptop, although seemingly very light, the screen cracked. I want to replace the screen for him because it is so incredibly expensive to have sony fix it. His laptop is a VGN-NR498E/S. are the procedures the same? do you think I can personally do it? I’ve never dealt with fixing non-software problems for laptops before. Thank you for helping me out.

Leo,
Not sure what’s going on. Sounds like a bad LCD screen. I guess could be a bad cable too, but I think most likely it’s related to the screen.

Great step-by step instructions, I was able to dis-assemble the lcd of my vaio vgn-fj270 to check for possible loose connections, but unfortunately the problem is still there…
There’s a black strip on the right hand side of my screen which has effectively reduced the resolution to 1000+ x 780+ or so… meaning the entire desktop is still visible on the remaining part of the screen at that reduced resolution most of the time. Strange thing is, when I lift up the screen at a certain angle or push it way back, the screen would sometimes become complete again.
Have you encountered a similar problem before? Thanks
Leo

Thanks for the step by step instruction. My screen was barely visible so we suspected either the backligth was gone or the inverter was not working. Luckily, the latter was the case.. A 60$ investment and this page saved my laptop.. THanks so much!!! Btw, Sony asked 100$ only to look at what the problem is. I fixed this by less than half of what they would have charged me.

stephen light,
Most likely yes. I’m not familiar with your model but I’m pretty sure that’s hot the latch is assembled. I’ve fixed a few of them on Toshiba laptops and has to remove motherboards.

Hi, Great info! I have a Sony Vaio VGN-TX770p that has a broken battery release switch. From my research online, it seems that I’ll have to go in from the top down and basically disassemble the whole computer to get at the battery release switch located under the mother board. Would you agree with this?
