Digital sat receiver colour problem

Hi, I have a Silvercrest SL65 satellite receiver, the one Lidl's sell regular, german origin I believe. When first switched on it is fine, but after a couple of minutes it will lose the red. Switching off and on will return the red but only for another couple of minutes. If the receiver is left on the red come back and stay, and that is the way it been behaving a fair while now. I used to repair tv's along while back. But I still have a fair amount of test equipment etc. What please could be this problem? I was thinking is it more like quartz crystal playing up? Help needed and appreciated thank you.

If it's not a silly question, if the red eventually comes on and stays on, why keep torturing yourself turning it off ... ?

Because it may be a long wait ( like watching paint dry, perhaps.). I had a look inside and I can see I would stand a much greater chance of diagnosis with the aid of a manual. The red disappears gradually over about 30 seconds. Switch off, switch on, always get's the red back etc. I switched over from RGB to CVBS in the menu and that works ok, crap quality picture now though. Thanks, David

That would indicate that the problem is in the red channel of the RGB drive circuitry. If the composite remains correct, then the decoding is working correctly. In the absense of a set of schematics, I think that about the only way that you might get a result, if you're lucky, is to have a pop at it with a hair dryer, and a can of freezer.
