Hi. Sometimes at random my twin famicom completely cuts sound but normally works once again after I slightly touch the av cable connected to the system. I've also tried many other av cables. Any idea's?

The RCA type connector for the audio jack has a cold/loose solder joint. Just open up the console and reflow it

I haven't opened it up yet, but it mostly seems to only happen when I switch to disk mode.

Mostly or only? I'd also think it's a cracked joint or bad AV cable.

It also could be an issue with the capacitor labeled C205 located near the audio/video jacks. If you remove this capacitor, you get clearer sound.

Do you notice that the FDS FM channel sounds muffled or not very loud? Then this is the issue.
