My Onkyo TX-DS575 Receiver reverts back to standby mode within seconds of the unit being turned on. A found a similar problem by a user on the net who said a resistor on the power supply side feeding the rear channel amplifiers had failed but did not specify which one. See link below for your reference: http://www.colin99.co.uk/hifi.htm Has anyone else had a similar problem, and if you could advise which resistor caused the problem would save alot of time. Thanks in advance for any assistance you can offer. Davo1
You can find it out by yourself. I have the same device; therefore, I know that this device has a "test" function. Just unplug rear (surround) speakers at first, then test the rest of the speakers if the amp lets you do it. Hook up one of the rear speakers you regularly use to rear left or to rear right in order to test each rear channel. If one of them turns off the amp, you'll be able to understand which side feeding resistor does not work. However, if the amp goes to standby mode as soon as you hook up one of those speakers, you can alternatively invert the relevant rear speaker's input ports for a while. (+ to -, - to +) Don't forget that you have to hook up the other rear likewise. This will allow you to cheat your amp for a while, and let you test your channels without taking care of ohms.
