White screen with lines
Hi, my Toshiba Satellite C55D-B5308 laptop fell off my bed and it started to display colored horizontal lines:
I turned it off and on again and it changed to a solid white screen with really-hard-to-see vertical lines.
The LCD is not cracked (I flashed a light while it was off and didn't notice any broken pixels) and flexing the upper chasis does not change the pattern.
I disassembled and reconnected the display ribbon cable, pushed the CPU a little bit, reseated RAM and also checked if the cable inside the LCD panel was connected correctly (it was, I reseated it anyway)
None of this fixed anything. I must note that it turns off automatically and connecting to an external display does absolutely nothing. Any help?
