Reply To: Problem sega master system 1 PAL


Hello all, I’m a new OSSC user! So far I’ve been quite pleased with the results with my various systems. Unfortunately, I’m unable to get any signal from both of my Master System consoles (Model 1 and 2, PAL).

Readout on the OSSC LCD: AV1: RGBS – NO SYNC
Info: Prof.9 1600×240

Both systems work great on a CRT TV.

Any idea?

Thank you for your help.
