My questions is: when a TV has no signal and the screen is pure solid black, are the pixels actually colored black or are they no color at all? When the TV is off the screen is black....

I'm house sitting for a friend and they have a 60 inch high definition TV that's about 2 years old. I was watching a movie and afterwards I turned off the DVD player, which made the screen go black, but forgot to turn off the actual screen. I've heard about burn in and all that, and now the picture seems darker now, but it is brighter in the room and maybe I'm just thinking it's darker out of anxiety. The TV was like this for maybe 12 hours straight and I'm hoping I didn't break it.

I looked up the TV type and apparently it is a rear-projection CRT type TV (I guess they were too cheap for plasma).

You did not say what kind of TV it is CRT? Plasma? LCD? DLP? They all work differently. In the case of CRT or Plasma, when the screen is dark, no energy is going into the phosphors, so no damage can possibly occur by leaving the set on with a black screen. In the case of LCD and DLP, even though the screen is dark, the pixels are energized. However, in these sets, there is no chance of burn in, and there is no permanent effect of continuous energization. So here too, no damage could be done by leaving the set on with a dark screen. You didn't break anything,

If the screen is black then you did no damage to the phosphor. I'm not sure what kind of projection you did this to. It could be CRT, DLP, LCD, LCoS or HD-ILA. The CRT has phosphor, no problem. The other formats use a lamp and the lamp maybe aged and it will become darker as it ages. LCD, LCoS, and HD-ILA has little panels and the lamp hits them regardless of the picture, and if it's black then they have to stop the light, so they get really hot. I never have seen this affect any format except LCD. And generally the blue goes first and you will notice a blue haze around the edges.

Yeah 12 hours can do that to plasma and projection televisions. Smooth move, you probably ruined the t.v. (no joke).
