Once upon a time not long ago, I accidentally plugged the wrong AC adapter into my OSSC. The backlight still came on but no menu. I know that it blew up the voltage regulator. My father was able to replace that. The menu comes up and I can select between the different inputs. I am trying to get it to work for my OG Xbox and PS2. But when I go to AV2 YPbPr, I still get NO SYNC and obviously no video signal. I also have some random instances where I get random characters on the screen. I’m not sure what to make of that.
I don’t know what to troubleshoot next or what board components I need to investigate in order to attempt getting my OSSC to function properly.
