Question about Harman Kardon AVR 235 Receiver

Open Question

Harmon Kardon AVR 235 wont power on at all. Stays only in standby mode.

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.

    Mine does the same thing. If you look into the top of the receiver through the grate on the far left side, you see a tiny little button. Reach in and press the button with something (not metal). This will reset the unit. Sometimes you have to do it a few times and mess with the power switch at the same time. Pain in the ****. I'm getting new reciever and never buying HK again.

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!!!

SOURCE: cannot get dts from my Harmon Kardon AVR 300 via my Blue Ray

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.

SOURCE: AVR amber light will not return to blue after

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.

Denon AVR-3200 wont go into standby mode


Not sure what you mean by standby mode. The power button on most of the audio remotes I deal with merely turns the equipment on and off.

There may be a short on the output side. Try disconnecting all the speakers on the back of the amp. If the unit stays on after that, turn off the amp and carefully reconnect one speaker at a time. Try turning on the amp after each reconnection. This might isolate any shorts that might exist.

My HK AVR 135 wont turn on. The orange light comes on but when i try to turn it on it does nothing. It has done this before and i ust unplugged it and plugged it back in and it turned on for a brief period...


Try unpluging the unit for atleast 2 hrs. The capacitors bleed off energy very slow, thats why it needs to be unpluged for a couple hrs. If that doesnt work it usually means the powersupply is going out.

Seems to be some sort of power problem since the READY light is no longer on, and therefore the remote control cannot turn the receiver on, nor can pressing the power on button turn it on.


If there is no standby light. Open the top cover and check the fuse on the primary power side. MAKE SURE THE POWER CORD IS UNPLUGGED.There are two transformers in this model. A small one for standby and a large one for the main section.A relay clicks when you touch the power button and switches on the large transformer and the display comes on. If there is any problem in the output stage the the relay will click and the system will go into standby again.
