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.

I have a VGN-TX770P. Screen cracked. Replaced it and now it’s dark (even putting back in the old cracked one is now dark). My tech thought is was the cable, got one, still dark. Now he thinks it’s the inverter. Three weeks looking and I can’t find an inverter. The guy in this thread had a similar prob, solved with a $60 inverter. Where can I find this part? I’ve looked online for two weeks, found one, when I went to order it they said it only came with the screen. Any help finding an inverter?

Kevin,
It’s possible that something got loose inside the laptop. I guess you’ll have to open the case and reseat internal cables and components.
By the way, did you have a chance to test the laptop with an external monitor? Will it work?

Mohd Bahij Ahmad,
I’ve never done it myself, but I really doubt that you can do this replacement.

I have a vgn-sz230p that the dog knocked of the coffee table. The screen looked fine but when I turned on the laptop it goes from bright white to black and back over and over again. I had a new screen so I put it in but it does the same thing.

Dear Laptop Tech,
I am just wondering whether is it possible if I were to attach a 13.3″ LCD of SZ series to a Sony T2XP/S(UK model equivalent of VGN-T in US) model of 10.6″ lcd series.
I tried to look for replacement of 10.6″ but they are too expensive compared to 13.3″ which are more common.
Assuming the port is the same, is it possible in term of motherboard power or graphic card power or of whatever reason that I do not know of. I am no expert of computer by the way.
Thank you.

Great writeup.
I was wondering if you would be familiar with upgrading displays. I have a VGN-FW370S with the XBRITE-ECO Display. I know that there is a superior, optional display, the XBRITE-HD from the factory on a different model number FW series. They are the same size displays, but different resolutions, plus the HD display has 2 lamps vs. the 1 in the ECO-Bright. Do you know if I can simply upgrade mine by changing out the LCD display and inverter and any sequential drivers?
Thanks,
Bryan

J Edwards,
Here’s what you can try. Find where you can change the LCD brightness settings and reduce brightness for the battery mode (when AC adapter is unplugged). Let’s say set the brightness to 50%. Does it help? Will it still go off when you unplug the adapter?

Ian Shuman,
Sounds like either a bad cable or LCD problem. It’s hard to tell without testing the laptop with another known good working LCD screen.
