20 Most Recent Onkyo TX-V940 Receiver Questions & Answers

Hi, Are all of the left side speakers out? If they are the receiver would need to be serviced. Thank you, Onkyo USA

It is likely the output power transistor is shorted.

HI check first the Dimmer on your remote or in the front panel . hope this helps to resolve the problem regards

How are you sourcing the program material to the sub? This TX-V940 receiver doesn't have specific sub support.

=== Just the same...

You need to first determine which is at fault - the sub or the receiver.

Connect the Sub Input to Tape Rec on the receiver (but DO NOT select Tape) and see if the sub reacts to your playing FM, for instance. If it works you need to go back to the receiver and the unknown method you're feeding the sub.

You could also test the sub with a CD player output but use a recording that starts low because you won't have volume control.

May be a blown fuse inside the unit. Disconnect from power, let stand 20 minutes to make sure the high voltage caps are drained. Open and look for a fuse near where the electrical cord goes in. Remove and test, replace if bad.

The fuse blew for a reason, apparently that has not been repaired.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

This indicates a load on the system, turn receiver off, remove speaker wires from the back of the unit. Now power up and turn volume right down, if the word protect stays off, there is a short in the wires or one of the speakers. But if the word protect comes on, "with wires and speakers dis-connected, it means there is a short in one or more of the audio outputs in the receiver. If you are handy using a digital meter then you may be able to track the shorts down, and replace the parts to get it up and running, also if you can solder then it will make the job easier.
