Bad soldering on the LM4766T amplifier IC's. A lot of work to disassemble, but worth it. Good Luck

Mine did this last year, turns out there was some problem with the soldering on the circuit board. Take it to be looked at, easy to be re-soldered and cost me about £50.

My onkyo HT RC330 will not power up at all. Have had problems past couple of months with starting it but if you played around with swith it would start. Now nothing.


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.

Unit wont stay powered up


Check for overheating. Place the unit in a large plastic bag and place it in the refrigerator for 1/2 hour. Don't allow condensation to appear on the unit before powering it up, the heat will evaporate any potential condensation. Put moisture absorber or rice in a paper bag in the plastic bag for safety to absorb any moisture. Then power up. If still inoperative check for DC or AC voltage on speaker connectors. If one side is different, or if DC appears on the outputs, audio output may be shorted. See if plugging in headphones stops the problem, some units disable the audio outputs with headphones plugged in.
