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.

@ Mike,
I’m not sure if these two screen are interchangeable, but you should search for a new replacement screen using the model number from the original screen.
Find the screen model number and search on eBay, amazon, google.
You have to be careful when replacing the screen on a Sony laptop. A wrong screen might fry the motherboard.

Hey guys. I have a Sony Vaio SZ 330P. I’m not sure how but my screen cracked. I am ready to replace it so I’ve been doing some searching on ebay and came across a screen from a SZ 650. Would anyone know if the SZ 650 screen and all the connectors will fit into my SZ330
Thanks.

Hi. I have a problem with my Sony Vaio sz series. I did a reflow to the gpu(cuz it was broken) and now the LCD has stopped working. I mean it has no backlight . If i connect an external monitor it works perfectly and the Gpu problem is solved… but now the LCD problem appeared.
Can u give me some solutions ?
Thanks.

@ Lorin,
Your description sounds more like the LCD screen failure to me.
Here’s what you can do to narrow down the problem.
Disassemble the display panel so you can access the video cable. Try moving/wiggling just the video cable while the laptop is turned on. Does it affect image on the screen? If not, this is not the video cable failure. After that try moving the screen. If lines change when you move the screen, most likely this is bad LCD screen.

Sorry – also, do you believe the SR190 will be similar in disassembling? I’m a newbie to laptop repair.

Thanks again,

Thanks for these instructions!
I have an SR190. Vertical lines on half of the screen. Pressure on the bottom of the cover or switching screen angle sometimes helps. No problems with external monitors.
Having trouble finding sr190 video cable – which I’m guessing it is based on this feed.
1) Am I likely correct?
2) Any suggestions?
Thx,
Lorin

Hi,
My sz750n has a problem with the backlight. The screen is very dark, but still I can use. I can see that win7.
I opened that. But there is no “ccfl backlight”,and I think other sz series don’t use ccfl backlight.
I think the problem is LCD cable. is it possible ?
What I can do to repair that ?

I can take pictures of laptop, if you need more details.

@ Brian,
I don’t think this is video cable related problem.
Did you buy a new screen designed for a Sony laptop? I’ve seen some sellers offering LED screens but they make a note it’s not for Sony laptops.
I guess some Sony laptops might require special screens.

I have a Sony VAIO VPC-EB33FM/BJ and I stepped on it and broke the screen. I replaced the screen but it is not lighting up. I can see it working in the back ground but it is dark. Should I replace the LCD screen cable? Is so, is it hard to do?
