This one probably falls into the "it should be obvious" category. Anyway, here we go:
About a year ago my laptop's screen was replaced because two parts of it had been damaged. When I received the laptop back, the new screen also appeared to have problems - but I couldn't do anything about it as it was a nonwarranty repair.
The thing is, I'm really not sure whether I'm looking at dead pixels, or hairs/dirt/debris stuck in the panel. There are 5 or 6 spots at the right center where random squiggly lines of pixels appear not to be working, and there's also a few other spots (one in the top left, one in left center, etc.) that are the same way.
So, is it possible to have hairs or other dirt stuck behind the panel? If so, what do I do about it? How can I determine whether that's the cause, or dead pixels?
