Question about Home Theater Systems
Can somebody tell me what the secondary voltages are on the main power transformer so i can possibly get a replacement.thank you hutty. I have a blown power transformer in my Denon AVR-1801 receiver. Denon wants almost as much as I paid new for the unit for the transformer. Does anyone have a more cost effective source?
I have a very similar problem with the same exact Panasonic sub. I went to Best Buy and Radio Shack looking for an adapter, and they basically told me that one does not exisit. Apparently, Panasonic designed the home theater system specifcally so that it could not work if any part of the entire system was ever seperated.

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section. Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multi-meter to check the continuity or shorting in components, if so detach from circuit and test. If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.
The processor must have the +5 voltage to the function properly, the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.
