My TV is about 2 years old. Never had a problem. Turned it on today and the color was abnornal. We seem to have no reds. Very green. I adjusted color and tint to no avail. Is there something obvious I'm missing?

Its so high pitched that some people can barely hear it, but I guess I have sensitive hearing. ... Anyway, this seems to be a fairly common issue and it is caused by either the ... You're probably hearing a transformer humming.
One of the circuit board ribbons connected on the vertical control is probably loose there is a few vids on you tube for this repair , failing that some of the driver capacitors need replacement with higher voltage caps same microfarad.
My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.
Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.
2 things have to happen. first, your tv has to be set for the correct resolution, second, You need to be recieving high def from your cable/sat provider.Your tv does not make programming high def, it allows high def.
if the tv is digital (high def) it does make sense its just a bulb most likely. if its analog it does not make sense. for a plasma or lcd with comparable picture to rear projection will be 5-6 grand and the colours will be comparable. less money will get you less than perfect colour and black levels on your set. only if your set is digital if not its a very different story if you need more help let me know i can guide into the right decision
I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.
The pixelation is probably caused by MPEG2 compression on the DVD and Virgin media video streams, the blur is probably caused becasue you are displaying a standard definition signal on a high definition TV.
However if a high-def source still has these problems then you may have a faulty TV, your best bet is too hook up a high-def source such as a HD/Blu-ray player or PS3/360 games console.
Should a high-def source look ok, then you may have some look changing the display settings on the TV to try and improve picture sharpness and color balance.
