Sony VGN-SZ640 Screen
Make note of the size and part number of the screen to be replaced so that you can find a matching display. Buying a new Sony VGN-SZ640 screen is easy, but it can take hours to actually replace the unit. It would be wise to take the old screen out first to help you track down a new one. The VGN-SZ640 screen is tricky to replace due to the fact that it is supposed to be part of the unit as a whole.
How can I tell if my Sony screen is about to fail?
- Screen blinks or flashes repeatedly
- Vertical or horizontal lines everywhere on the laptop screen
- The screen does not light up
- Only part of the screen area lights up
