Question about Audio Players & Recorders
Pulled fan continunity ckecked out, but fan is intermittent with higher out put. Is there a 'feed back' in the fan circuit that determines if fan is operating before overheating gets critical? Will replacing the fan motor fix the problem or is it deeper in the circuit?
From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

It probably needs soldering of the voltage regulators and/or output IC.
I think that model has an access panel on the bottom (it may need to be cut out then rotated and screwed back on when done).
If it doesn't have the panel the main circuit board needs to be taken out to access them.
The regulators and output IC are mounted on the main heat sink. a little soldering and it should be good as new.

Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.
