I get no video at all, it could be as simple as a dead RF modulator I suppose. When I had it apart, I noticed a couple of different sized electrolytic caps in there. How susceptible are 20 year old electrolytics to drying up? I'm thinking of replacing them, definitely on the dead 2600, and possibly on the 4-switch one, which works fine but has a weaker signal than the 6-switch. Hrm, if replacing the caps doesn't fix it, what should I check next? I've got know good ICs to swap with, but is there anything else I should check before swapping chips? If I put a chip from the dead one into the working one and find it's a bad chip, how likely is it that whatever killed the bad chip would kill its replacement? I wish I knew more about electronics... I got as far as Ohm's Law, crystal radios, and a really rotten-sounding homemade distortion pedal for my guitar, then I got into software...
