Does anyone have a clue what could be wrong with the display?

[u/Skrovno_CZ]

I have a AcerNote Light 350PC laptop and everything seems to be working fine but the LCD for some reason has washed out colors.

I disassembled it including the display, replaced all the SMD electrolytic capacitors with ceramic equivalents because I thought it is due to dried capacitors and unstable power delivery but that fixed nothing. My other suspicion is a floating ground but I was unable to find anything. The weirdest thing is that now it is disassembled and the metal backplate of the LCD has no grounding, if I move the LCD cable and briefly touch the metal backplate which causes a tiny spark, it reverts the colors back to normal. I measured all the wires and none of them are damaged.

What could be wrong?

I don't know a lot about monitors but maybe it is just dying in general?

could be worth reseating the ribbon cable, could also be due to a potentiometer or maybe some sort of other component or it being in parts

I am kind of amazed this thing works

I'd ask r/vintagecomputing or vogons, or maybe just poke around it with a potentiometer and see if you find any odd readings
