Hi,
For the past several months the colors on the screen (all channels) will momentarily change to all reds,greens,blues. This will typically last for 10-15 seconds and then clear instantly. During this the sound is fine and the picture sharp. It will happen every 15-30 minutes or sometimes not at all--very random. We thought that the television was the problem so we bought another one but it still does it. I removed a dvd recorder to test and it still does it. From my limited knowledge, all that is left is either the receiver (DRD420RE), the LNB or the coaxial cable. Any thoughts to where I should start to trouble shoot??
