Blown Video DAC?

Today I plugged my Dreamcast into a scart switch box, which didn't work. Strangely, when I turned my snes on, it actually sent power through the switch somehow, powering on my Genesis...!

After plugging my Dreamcast back in directly as it was before, I get audio but no video. Did that switch just blow my Video DAC? Is there a fuse or something that I could look into before replacing the unit? I looked over the motherboard and there are no blown caps or obvious damage.

The Snes and Genesis are fine luckily.

 

Cheap scart switch boxes do this, you shouldnt use them

 

Yeah, I read all about that after the fact. It's probably common knowledge outside of the US.

 

Only fix is replace the video DAC. Sorry about that. -_-;

 

Thanks for the response. I ended up fixing it by replacing the motherboard.
