Recently we've been having problems with the color on our TV. The color and picture are fine when you first turn it on, then about 10-20 minutes into viewing, the picture "loses" it's red color/hue, and the image is then only in greens and blues. The image itself is clear, so it's just a color problem. If you turn the TV off for 30 minutes or so, it will turn back on with full color, but will again lose the red color and go to the green/blue screen after a few minutes. It seems like the length of time that the screen stays in full color is diminishing, so something seems like it's "going out" for lack of a better term. Any ideas would be greatly appreciated! Thanks!

Re: problem with color
Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck

Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner. Contact local tv repair shop to get color wheel replaced in tv. Thanks.
It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.
