I'm a lurker for years and today I decided to make an account because I've got a question.

There are no shorts, no solder bridges, no cold solder joints, etc. I have checked everything for continuity and the DCHDMI's self test shows me lots and lots of hearts.


Do you guys have any ideas what else I could check? Primarily the Dreamcast was intended for playing on my OLED screen, but I don't want to give up the option of being able to play on the CRT. Could it possibly be that the mod is doing weird things on a PAL Dreamcast? Or is the video mode somehow altered when the DCHDMI is installed so that not every CRT can handle it anymore?
I also found some other people having the exact same problem. They never found a solution. Maybe I misunderstood something and the AV Out is only working for VGA output with the DCHDMI installed?
I hope someone can help me!
