I have a great fully working French/Scart Colecovision.
My problem is coming with the Module #1 : when plugging it, I just get a black screen and it won't read any game cartridge.
Unplugged, I get my Colecovision back as usual...
I already cleaned up the connectors many times, both in th extension slot and the Atari module, and did not identify any other potential issues.
Anyone can help ?
