Horizontal Flickering white lines all the time?
Trying to refurbish this laptop, getting this chunck of white/coloured horizonral pixels flickering when the screen is on. Are we thinking new screen or just the flex cable?

Flex could need to be replaced, but I would aim on graphic card issue.

To troubleshoot a flickering screen, first update the video card drivers, and then make sure the CPU is not overheating or being overclocked. Then connect a second monitor to the unit.
- If the same flickering happens on the second monitor, then the first computer’s monitor is not the problem. In this case, replace the video card or the flex cable.
- If the second monitor is fine, then the first computer’s monitor is the problem. In this case, replace the screen.
