Batboard

I have a CDM1250 that was working one day, and then not the next. It will not power on at all. I've troubleshot the fuse in the head, tried another head, and made sure the radio isn't set up for ignition control (never was). Can anyone recommend other points to troubleshoot? Are there any fuses on the board like the GM300s, etc?

Thanks
Jay

See J0401 were the control head connect to it may have bad solder join on the pin, if this dont work check Q 0641 it may be open..
