Question about Thomson Televison & Video
I have a Sharp 56dr650. The color wheel bearing failed. Sharp cares not for its customers and won't even respond to my pleads for help in obtaining the replacement. So, with that said, I went to ebay and bought a vizio color wheel (Omega TV in Hollywood, FL). Color wheel is incorrect and colors are all blue as is, so I pulled the color wheel off and did the same from the old one-BIG note, the wheels are glass and fragile, DO NOT BREAK the old color wheel! I viced the old bearing and carefully worked the shaft out of the bearing (it is snapped into the bearing). The vice distorted the old bearing but it was trash anyway. The new bearing, I broke the new color wheel off and viced the shaft. I then pulled the old bearing from the wheel. I then carefully push the old shaft and color wheel into the new bearing (you will know when it snaps in place) asserting preasure ONLY on the metal center hub with my thumb. I had to file a new slot on the cast housing as the ribbon connector is about 1/2 inch shorter on the new bearing. I installed and it all works great!!! Saved from tossing a $2,000 plus tv out! SHAME ON SHARP! Never buy another Sharp product!

SOURCE: color blinkig in and out.
It seems like the color wheel might start to fail.
Do you hear any abnormal sound(s) from the TV when ramdon color appears.
Would you be able to check and make sure all the fans are working properly?

I have the same problem, TV is only 3 years old. Already replace bulb once and helped for a little while. The more I check, this sounds like a very common problem. Hmm...maybe a class action suit?

Yeah could be expensive if it isn't the lamp.
Mind you could be a little easier, might just be a fuse on the video relay. If you are confident in being able to open it up, check the relay that runs from the video input to the power capacitors and there should be a small fuse along that circuit.
If the fuse has a broken capsule then you may just be in luck. Failing finding a broken fuse, then I would agree with you on the bulb. But check the blub for any markings or cracks because they usually only make noise when the vacuum fails.
Hope this helps and good luck mate! :D
