Hmm well if cleaning all your contacts and ensuring your RF box works (switch it to game and try an atari or NES) doesnt work then idk what to tell you. Schematics would be nearly impossible to come by unless Coleco released them years ago (doubtful) and even then you would need to have an electronics degree to understand them (RF circuits aren't the easiest btw). Also many of the components used may be obsolete except maybe some 741 opamps and 555 timers (so popular they are still in use today).
