I just bought one too, was playing X-Men vs street fighter on the SEGA Saturn and was happy with it, and after an hour or so of game play, all of a sudden the picture went and just gave me audio. I pressed the av1 button to get the picture back and it showed up but after a few seconds paused or not the picture would go to test screen.
I notice the LCD on the ossc was flicking between different things and it didn’t seem to hot to me. Now it doesn’t display anything. I bought it on eBay and I’m guessing I’ll have to do the whole return BS. But I also just bought a kiaco branded ossc. I was hoping that the ossc would be the answer to the problem of a cheap hd converter having the same problem but at least I got a few months out of that one haha.
There’s obviously a heating issue with this thing so I’d like to see an answer to this from someone
