Can a failing DLP chip cause graininess?
My WD73-737 has developed a few stuck mirrors, got new chip on the way, but I've also noticed that solid black screens have gotten super grainy and less black. Overall the picture doesn't seem quite right these days.
The other day when I turned it on all I saw was this weird green hue on the screen, no picture no menus. I shut it off and came back later to check and it worked fine again.
Is there something else that could be wrong with my tv? I'm still on the original lamp since 2009.
