Question about Projection Televisions
Our television makes a loud whirring noise at the back of the set and then the power button lights up "fan" and "lamp" and then at the bottom "system" something. It looks like a mad face. Two eyebrows and a straight mouth. The color starts to go and then it eventually turns itself off. Help.
Well if its a Sharp 65DR650 model then your color wheel is shot. The color wheel spins and it wears out on this model television. I had the same problem with two others and multiple others had same problem on the internet. Our had the noise and after being on a while the colors started messing up then it would shut off. To fix it you need to get sharp to release a light engine to fix it. But when we checked they were backordered with no sign of any ever being shipped. So we junked the two sets we had.

Without a model number, i can't be much help. if this is a newer dlp or similar tv, the fan is probably going out. some newer tv's have a fan that is part of the light assembly, some have a separate fan.. the loud whirring noise is usually caused by bad bearings or the blades of the fan may have become unbalanced, either way, the fan making the noise will need replacing. the color going is usually caused by the lcd or dlp overheating and/or the lamp overheating.
if the tv is out of warranty, remove the back panel, locate the fan making the noise, and search for a replacement. if you have a model number, i can check around and see if i can find the part number for you.
hope this helps,
