Question about Pioneer VSX-D488 Receiver
When i power the receiver on it says power off and then automatically shuts off.. No speakers or anything are hooked up...how do i get this receiver to work?? Any help would be greatly appreciated
One of the power amp ICs has blown and the receiver is sensing a DC offset on the output stage. The ICs are available for around $40-$50 but must be soldered into the circuit board. All five output stages must be measured for DC offset to find out which chip is bad before the receiver cuts off. The voltages involved are dangerous and this should not be done except by someone experienced with working on live equipment.

If the STANDBY indicator blinks and the power shuts off
automatically, take the unit to your nearest Pioneer authorized
service center or your dealer for servicing.
