Hi everyone, I've known about this forum for a long time but never really needed help until this moment. I figure maybe someone can give me their best guess before I dig further...
I have a Toshiba L75D here with a screen that is acting up. I was told that there may have been pressure put on the display.
So i took apart the display assembly, and jiggled the LCD cable to see if it made any changes to the screen. Nothing. So I was guessing it wasn't loose and is just the screen.
Replaced screen. I booted once and it was fine. Turned off to reinstall all screws etc. Turned back on, same issue as before. Odd.
So now I'm thinking maybe it is the LCD cable.
It's hooked up to an external display, so for sh-ts and giggles, I try to 'extend' the displays, rather than duplicating them.
The laptop LCD now works fine.
I maximize a window. The laptop LCD goes white with lines again.
I choose second display only, then back to duplicate and the laptop screen works again. I can repeat this to infinity.
I'm wondering if anyone can give me an educated guess as to whether or not it may be a driver issue, or if it is a video card issue (I'm hoping not).
It has a discreet video card - AMD 8330 I believe. I have rolled back drivers, didn't work. I have uninstalled all AMD software entirely and it is now running on a generic video driver. No luck.
