Question about Audio Players & Recorders
I get an error when i turn on the system saying push power, protect. we have taken the unit apart to see if there is anything obvious but all we found was that it was covered in dust. can you help?
The 'protect' message indicates that the units thermal protection mechanism was activated and has cut output to the speakers. Causes vary, but the idea is that there is some problem with the impedence from the speakers to the power amplifier part of the receiver. Could be that the speakers are wired incorrectly or that they are just actually too powerful for the receiver to properly supply.
So check the speaker wiring for positive/negative polarity, frayed wires, disconnected wires, etc., or try to disconnect them all together and see if the receiver starts.
If not, other causes could be blown fuse (cranking the volume too load could blow a fuse). So you might want to check for any servicable fuses in the unit and replace any that are blown.
The thermal protect circut can just activate on its own and reset on its own. This might indicate that the unit is faulty or just got over heated (try moving the unit away from a heat source - or allowing proper airflow around it). If this circuit is faulty the unit could need repair.
Hope this helps.

The first thing I would do is take the cover off and blow it out with compressed air. Sometimes that's all it takes. If not, look for corrosion everywhere you can. If there is corrosion it will have to be removed. If it's on any legs of capacitor, all those capacitors need to be replaced. Other than that, I'm not familiar with it enough to pinpoint a particular failure from your description.
