/vr/ - Retro Games

So while trying to set up a new tower of power, I ran into a snag with my model 1 sega genesis. Using a third party AV cable, I wasnt getting video but sound was working fine. Tried this on both my main CRT television a smaller CRT and a modern flat screen with all the same results.

After some troubleshooting I tried to fiddle with the cable at the back of the genesis and got video to work for a short while only when pressing hard. Letting go made the video vanish. So I'm thinking its either the 3rd party cable or the console itself. Just want thoughts from more experienced collectors or experts when it comes to internals on these retro consoles.

For reference this is the "High Definition" Model 1601 with TMSS.
