Any responses would be appreciated Thanks.

The RF box soldering is most likely loose and needs to be resoldered. Geminis are notorious for the soldering to become brittle overvtime and the system was built with off the shelf parts.

I am probably going to hold off on trying to fix this system for now because i have 4 switch woody coming in the mail. This is actually my first atari playing console and I would like to get it functioning without breaking it. Does anybody happen to have pictures they can use to show which solder points I need to reheat and maybe some step by steps I could follow? I know I would certainly appreciate it and others would too considering I really couldn't find instructions for this fix on Google or AtariAge. If you have a link that's fine too.
