Hi, im not expert but I will try and see if I can help.
1: Tried moving that tiny black switch next to the RF putput? I'm not totally sure what it does and what it's for but maybe woth a shot.
2: Not quite sure how to fix theis unless the outputs needs cleaning. If rusty then maybe some fine sand/glass paper would help, mind you this may be good for point 1 too.
3: Iv experianced that with my CD32, strange stuff but sorry I can't help there. Maybe a power supply problem? :-?
