there are a few stains in my lcd, I bought it 2 days ago and i assemled it myself. This stains move, merge and decompose ( stains' last locations are restored) or they just disappear and appear because im not sure but this happens in a loop for a long time.I ordered this lcd model N173HGE-L11 but seller posted HSD173PUW1 i dont know if it matters.
So are they dead pixels or stuck pixels ? Or a lighting problem in lcd ? Maybe, i have broken something while assembling it
