WOW..Could not even guess on this one..."somewhere in the radio" is a very broad guestimate....

Lights on?
Display work?
RX work?
ALL Dead?

Well if it works on an external supply , it can only be one thing..The voltage regulator and or regulator circuit. Unfortunatly I have no schematic or know where you can get one. I can fix it for him if he would like but can't assist this repair on the Forum unless it is in front of me.
