When there is no color, the black and white picture has a noise in it that appears like you're looking through a screen door. Both the main picture and PIP will lose color. When I remove the rear cover to work on it, after 10 minutes or so the problem won't occur anymore. I have tried to heat up the pc boards with a hair dryer, but the symptom won't return (until I leave). I suspect the comb filter. The customer normally watches digital cable and he has had the cable box replaced. I have asked the customer to try using his DVD to see if it loses color as well, but so far the results are inconclusive. Thanks in advance for any help.
