Hi all: I purchased one of these for cheap, was very dirty. The following problems are present: - CD player does not spin, track indicator does not light up. (Lack of power to CD mechanism?) - TAPE/RADIO/CD slider was scratchy, but that cleared up after compressed air - Tuning dial was stuck. I tore down the unit and deep cleaned the housing and blew the dust off of the PCBs. I reassembled the unit and plugged everything back in, and the following problems are present after complete teardown: - CD player (same as before, but track indicator lights up for a few seconds and then shuts off) - No audio (When volume potentiometer is turned up all the way you can faintly hear the station if you put your ear close to the unit.) I have to think that somehow the amplifier is not turning on to create the lack of output, but still being able to hear the audio at a very low level. There are no fuses in the unit that I can find, the amplifier did work before I took the unit apart. I'm stuck at where to go next, any help is greatly appreciated.
