Denon avr-1604 +45volts at all output transistors

[floydturbo]

Unit goes into standby. It appears that all output devices are fine, but 45volts +/- at output due to high voltage at each of the transistors. Why would all they all see such high input voltage to the transistor??

When the outputs are infact ok, the plus/minus rails present at the outputs are either the loss of bias control(latched circuitry) OR it may be leakage back through the protection circuitry. Depending on the design/device used, you should at least read a balance of +_ .5 to 1.5 V at the base of txixtors.

Common bias control problem are open (low value) rsistors supplying the said circuitry---unless have experience & can spot check w/out documentation, need to get a schematic.
