Onkyo ht-rc330 only clicks and will not turn on

All such devices remember the last settings. It is the way they are made. Stand-by normally only works from the remote.

First thing to do is to disconnect everything from the received,, and take it to another AC outlet to plug it into, and try again.
The unit does not have an external fuse, and it is not recommended to open it.

Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.

Hello Billy, I would advise to try a factory reset of the unit. After the reset see if you are getting test tones out of your speakers in the level calibration menu. If you are not then the receiver would have to go in for service. Thanks, FJD

Unwire the receiver completely. Then rewire, ensuring that the speakers wires are correct. Make sure that the main power cord is properly connected. If problem persists, upgrade to new (and better) receiver.

Do you have a optical/coaxial input on your system? Eg: cable, TV.I use a optical input on my Yamaha ( cable, satellite ). Look to see if there is a optical/coaxial output on your pvr, there should be. Use ether the optical or coaxial output from your pvr and connect it to the cable (satellite ) optical/coaxial input on your receiver. The manual that came with your Shaw PVR should explain how. You will get 5.1 surround if available on certain channels.I prefer optical over coaxial myself, but they both work well.If you don't have optical/coaxial inputs on your receiver, you will have to use RCA cables, analogue out on cable box, to tape input or aux on your receiver. You will not get surround sound, just stereo. But it's better than nothing.

you may need an extra amplifier for your subwoofer.

No! I'am afraid not, if you have checked your wires carefully and it checked, the audio output semiconductors will require a technician to remedy the problem.

I have the same problem, anyone slove it?
