I followed this video in order to mod my 4 switch 2600. Same mod and same 2600. I kept getting signal degradation coming in and out. I decided to remove q201 and that solved it. I would definitely recommend removing q201. I hope this helps anyone else out.
How do i turn rca to composite? If i plug a dvd that says composite out to a composite in it works fine but when i plug a RCA it does'nt work on a composite in but works on a RCA in with no problem
