John:
? ? My QMX is an original Rev 1 bought at Dayton the week they came out. I was using my standard 12V supply that I have been using all along with the radio. Now the power supply board in question is the one on the Left. Now as an update I might have a clue as to what really happened. When I took things apart I noticed there is a SMD that is right up against the bolt holding the Power Supply in place. Seems that bolt shifted and that SMD broke free from one of it's pads and was floating free. I quickly soldered it back into place but no Joy. I'll spend some time this evening and measure the diodes and the resistance to ground as you pointed out.?
? I do have a second kit so maybe it's time to start building :)?
? Thanks for kind response.?
