I have an ICOM 7000 with the LDG AT 7000 tuner and a sec1235M power supply. I used it on a limited basis in Houston with no problem. I had to move and boxed it all up and put it in storage because I just couldnt operate in the HOA neighborhood. 4 years later I've moved and unboxed it to get on the air. I connect everything and it will not power up. 1235M registers 14 volts static. I've cleaned the fuses and tried the cpu reset. All connections seem to be good. 14 volts does arrive at the radio end of the power cord. I'm stumped. My next step is to send it our for repair but I wanted to see if anyone has encountered this or maybe has some suggestions. I tried it in my vehicle(while it was running) and nothing. How can something be working when you put it away and then not even power up? This machine is pristine and looks brand new. I didn't get to use it much and most of my use was just listening in since I couldn't transmit very well in the houston neighborhood. Any insight or suggestions would be appreciated.
