In the following guide I will open up the display panel and remove LCD screen with inverter board from a Sony Vaio PCG-K series laptop. As an example I’ll be taking apart a Sony Vaio PCG-K33 laptop. These instructions should work for many other laptops in PCG-K line.
By the way, in one of the previous posts I explain how to access the power jack.
There are four screws securing the display bezel (mask) to the LCD cover. These screws are hidden under four rubber covers. Two black covers on the top of the bezel (marked with yellow squares) and two white covers (marked with red squares).
Remove two white covers on the bottom.
Remove two black covers on the top.
Remove four screws found under the covers.
Now you can start removing the display bezel as it shown on the picture below. Carefully release the bezel from under the hing cover with your fingers.
Continue removing the display bezel.
Finally, the display bezel has been removed.
The screen inverter is located below the screen. There are no screws securing the inverter in this model. The inverter board simply glued to the screen cover.
Carefully unplug cables from both sides of the inverter.
The inverter board has been removed.
Now I’m going to remove the LCD screen.
Remove six screws securing the display assembly to the cover.
Now you can separate the screen assembly from the cover and access the LCD cable. The LCD cable has to be unplugged from the screen.
Remove the yellow tape. Carefully push on latches securing the LCD cable and pull the cable from the connector.
After that you can separate the display assembly from the cover. As you see on the picture below, the mounting brackets are still attached to the screen. In order to remove the brackets, simply remove four screws securing them to the LCD screen.
Finally, when the LCD screen is removed, you can replace it with a new one if needed. You can find a new LCD screen for your Sony Vaio PCG-K laptop here for less than $60.

How to disassemble Sony Vaio VGN-TX770P/W series laptop
July 28th, 2011 at 7:10 pm
I have a Sony Vaio PCG-614xxx with VPCCW21FX screen. My laptop screen got cracked, and to repair the screen, I was asked by Sony rep to find the screen model by opening the screen but had no clue how to. Thanks to this post, I am able to open the screen, find the model number, and take my next steps.
Thanks.

Joseph,
I haven’t created instructions for Sony Vaio E series yet.
Could be similar to this one: http://www.insidemylaptop.com/replace-lcd-screen-sony-vaio-nw235f-laptop/
But this is just a guess.

Hi, I have a Sony Vaio E Series and my display got cracked and I need a replacement. Do you know if the procedure to change the display is different?

Great site and found the photos of disassembly a useful guide even though my machine is a Sony PCG-GRT896HP.
My screen started flickering when moving it a few months ago, so suspecting the screen cable, I left the screen up, since I never move the laptop. Everything was fine until this morning – blank screen! Removed trim and checked cable and inverter connections – no joy.
Found that after closing lid and opening, screen would be okay (albeit with a red cast) for about 3 seconds, flicker, then go blank. An image is barely visible and it still displays to an external monitor.
Realised problem is associated with the microswitch that dims the screen, but have no idea how to proceed.
Any suggestions would be really appreciated.

michael,
I think you should use your original inverter. It’s just a different type of connector.

I ordered a replacement screen for my PCG-7112L. It came with an inverter attached but uses a larger connection pin for power. Should I just remove and use my old inverter or should I seek to change the power cable from the laptop to match the new inverter?

Hello, I find your site very helpful and I would like tot ask you an question: I’ve got a PCG-K115Z and I want to put 2 x 512 MB memory into it and a larger & faster HDD. But I can’t let the BIOS recognize the changes: memory never comes above 768 MB and the new HDD does not work. I updated the BIOS to version R0110X1 but no result.
The old HDD is: Hitachi DK23FB 60 and the new one: Samsung Spinpoint HM160HC.
I thought the BIOS would recognize the changes in hardware automatically but it can’t forget about the old configuration. How can I “clean” the BIOS without damaging everything?
Thank you for your answer!

Greg,
It’s either bad inverter board OR backlight lamp problem.
For some reason I think your failure is related to the backlight lamp, not the inverter. This is just a guess but from your description if feels like the backlight failure.
Check out this guide for testing inverter/backlight failure:

In order to find out if your problem is related to the inverter or backlight, you’ll have to test the laptop with another known good inverter or backlight. There is no other reliable way.

Wow! What a helpful site! You’re one of the real pros on the web!
I’ve got an old Vaio PCG FR-130. The screen started fading, looking like a dim amber color. It would blink out after 10 minutes but if I used a paper clip or closed the cover on the cover latch it would appear again, although less than optimum brightness. I did some study and found out it might be the inverter. Any at home diagnostics I can use to test it, repair it? Thanks.
