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.
Using a sharp object (or small screwdriver) remove four rubber plugs. There is on plug in each corner of the display bezel.
Remove four screws found under rubber plugs.
Start removing the screen bezel as it shown on the picture below.
Continue removing the bezel. Be careful, do not apply to much force because the the screen bezel is made of thin plastic.
Remove the screen bezel.
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.
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.
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.
