I am getting the dreaded blinking light on the GCDual I got from Castlemania games (which is believe is Blackdog's version) so hoping I can get some help here. I have literally purchased two of these damn things thinking there was something wrong with the first. I'm at a loss, so hoping someone can provide some more advanced troubleshooting besides continuity testing the hookup board (which I have checked every combination possible). I don't have an oscilloscope atm but this might drive me mad enough to finally buy one.
Issue regularly blinking light, no video or audio via HDMI.
Configuration
I removed the two Chroma circuit resistors per the jumper guide, other than that nothing else is out of the ordinary.
As I noted I purchased two of these and as such have painfully removed that hookup board more than once and carefully resoldered and checked all connections. All of the native outputs still function without issue so I'm hoping there is a better way to isolate the cause of the issue else the only thing I can think of is to ditch the hookup board and maybe design a flex cable to replace the hookup else hardwire everything.
