I have some consoles I'm trying to repair and hope somebody here could help, they both are AV modded with a transistor and two resistors.
First I have a PAL Junior console that works and plays fine, but the picture is always pretty dark and there seems to be ghosting interference. I tested to install a new AV mod just like the one I already made in case I messed up the first one, but it was the same problem, so what could be wrong? I don't know if the picture looked fine before I AV modded it cus it has been laying around for a while.
The next console is a PAL 4 switcher that acts werid, sometimes it plays and works fine with no issues at all but most of the time it glitches pretty bad, like characters are stuck and in the wrong place or jumping around. And when it glitches the screen can kinda like loose color and flash and jump a little bit. Any ideas what might be wrong?
