Started tearing into the 11/780 and pulled the 11/03 and the RX01 out to clean and test.
Looks like the PS is bad in the 11/03. It powers on and the fans run because they are AC
but I am getting sometimes 4.5 volts on the 5v line and 0 volts on the 12v. I have 34
volts coming out of the diode rectifier. I suspect switching transistors.
Anyone have experience with these?
Brian.
