Question about Onkyo TX-SR304 Receiver
My Onkyo TX SR304E has just developed a strange fault. The volume starts creeping up by itself. Any ideas as to how I can fix this? Usually have it on 25 - but it gradually goes up to well in the high thirties - when we have to turn it off as its too loud.

SOURCE: Hi I have an Onkyo
The unit is in protect mode. A problem was detected in the final stage of the amp and the unit shuts down to prevent further damage to either the amp or speakers. Check the speaker wires to be sure that they are not crossed anywhere. If with the sepaker wires disconnected, the amp still enters protect mode, the problem is internal to the amp. This is usually defective output transistors. Expect a parts cost between $15-$40.

what u can utilize on your tx-sr304 is the optical input at the back of the receiver. connect an optical cable from your PS3 into the receiver then follow these steps:
*make sure that the digital input on the front panel of your receiver matches where you placed the optical at the back of the tx-sr304 (either OPT1 or OPT2)
*all you have to do is keep pressing the digital input at the front panel until it goes to OPT1 or OPT2 (preferrably stay on DVD mode)
AFTER completing this go to your PS3 settings:
go to settings / then go to sound settings / then audio output settings / then set it to DIGITAL OUT (optical)/ then play and enjoy.....ü

These units *(if I remember correctly) had a problem with a memory IC in the surround porcessing section that would show up initially as popping and would eventually end up with no sound at all. This is a straightforward repair that involves replacing the IC with a new one (different manufacturer). The problem is that this is a surface mounted IC and is difficult to replace without damaging the underlying PC board. This is NOT a DYI repair. Have this unit checked by an authorized Onkyo service center.

Check the impedance of your speakers. It sounds like the amp is getting overloaded and shutting down either for over current or over heating.
Most common issue is a partially blown speaker or crossover.
Sometimes it's just a rogue strand of wire, and reconnecting everything fixes it.
But measure the impedance on all the speakers anyways!
