Question about Harman Kardon AVR 235 Receiver
My HK AVR 235 wont stay on. The orange standby light shows and when i press the power button to turn it on, it only clicks (relay) but doesnt turn on. No display or sound show up at all. I also noticed the blue LED on the power button is dull. Please help.
Ive tried unplugging it, the reset but with no luck.

CHECK YOUR WIRING!!! I have had problems from time to time, generally after re-arranging, and have found speaker wires slightly touching on 1 channel caused my AVR to give similar problems. GOOD LUCK!!!

I'm not sure if this solution is still necessary however:
I own a H/K AVR300 and have a PS3 hooked up via HDMI to the TV and Optical TOSLink to the receiver. I have no troubles selecting between DD 5.1 and DTS 5.1. I can even select trueHD whatever format but I can't detect an audible difference, I think that mode might be downgraded back to regular DD5.1...
Hope this helps...

Ensure that your speakers are connected to the terminals that you have your speaker selector switch turned to.
Then check that you have your device, whether it be a CD or DVD player, or turntable, plugged into the correct input and that you also have the correct input selected on the receiver.

There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.
