hdmi sockets are faulty on the dsp board - repair - replace dsp board

I would at least disconnect all units from power for a while and then reconnect to allow the units to reboot.

Your unit is going into protect mode. More than likely because you have a bad channel. Take a DVM on diode check and test all off your outputs. Once you find the pair that is shorted, you will need to replace both outputs and all of the transistors in that circuit. You will also need to check your low ohm resistors in that circuit as well as your duel emmiter resistor.

There are plenty of protect circuits in your receiver. Each chanel has one as well as dc protect and thermal protect etc etc. More than likely you have a blown channel that needs to be rebuilt.

change the capacitors on the audio board

Check to make sure the speakers are secure, if everything is fine! the problem is in the audio output ic's in the receiver. This will need a technician to take it further to find out how much the cost will entail.

You must first buy a multi-component remote such as an lg harmony 550

You can hook as many subs as you like since the Onkyo only provides the Pre-Out Line Level to the amp(s) that drive it (them). I run two myself.

Bi-wiring is a personal choice and some swear by it while some of us swear at it in a modern home environment. The premise of bi-wiring is that your amps or crossover networks **** to start with so you have to do all this work-around.

My $.02 is you add complexity, waste speaker wire (which can be expensive if you subscribe to the theory that wire can change the sound other than at the cash register, but don't get me started on that), amplifier resources, and MAYBE you'll think you hear an improvement. Perhaps if you lived in an anechoic labratory you might. I think it's a crock.

If you look at the second diagram you'll notice the fundamental electrical circuitry of the speaker wire is essentially unchanged except you now have twice as much speaker wire. The same amplifier output posts still feed the same speaker input posts. How can this be electrically different?

You'll rarely find anyone who can produce a measured audible difference with any of the snake-oil schemes to get into your wallet. It's always flowery prose and faith.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

A receiver with the specs...

* "90 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven from 20 Hz to 20 kHz, with a maximum total harmonic distortion of 0.08%"

(*) The only acceptable statement of its power bandwidth in the manual.

... when fed an undistorted audio signal, used properly and not driven abto clipping is not particularly dangerous to any reputable speaker.

Driving any amplifier, even a modest one, into high distortion is more dangerous to any speaker than a high-powered amp pumping pure undistorted power.

Choose any speakers but low efficiency models if you want loud and clean sound.

What sound from what source? Is the TV the source of the sound ? If so, why? The best TV-related sound would be had from the cable, dvd, bd or whatever else it is showing. Your TV could be the reason you cab't hear it.

What still works? FM? CD? Have you cracked the manual to see what it recommends? How about running through the basic speaker setup again to see how that works out.

Here's a few quick things to check.

Turn on the tuner and see if sound comes out, that will indicate that your amp is fine and you may have lost or changed the digital input settings.

Make sure the Multi Ch. Button is not pressed, ensure that the tape monitor (if it has one is off). Check that the volume is at a reasonable level and that the mute is off.

Change inputs between your different sources to allow the digital signal to re-lock.

Still not working?

Unplug the unit for 10 minutes then plug it back in. Now repeat the above steps.

Still no go?

I will look-up the reset proceedure in my database for you.

Hope this helps!

Cheers,

I recommend you double-check all your speaker wires at the AV receiver and at the speakers. It is very common for a single strand of copper wire to be loose, and this strand can short out to the case or a nearby connection, which in turn will cause a protection fault and cause all the channels to be silenced.

Additionally, most amps sill have a 'tape monitor' function, a relic from the days of recording albums onto cassette tape. When this button is mistakenly pressed on the remote or the front of the unit, an easy to miss 'tape monitor' light with go on on the front of of your receiver, & it will appear to be working normally but will produce no sound until 'tape monitor' mode is deactivated.

Both of these solutions are very common, and very free to fix.

I hope that helps.

There are several ways to do this. Here are the two most common.

The best results will be provided by connecting the component cables directly to your TV, including the audio cables of course, and then connect a separate pair of cables from the TV "audio variable out" to the audio in on the receiver.

However, if you do not have that option then connect via component to your 604 to inputs on the panel labeled "component video in." Then, connect from the monitor out section of the 604 via component to your splitter, cable box etc.
But again...the BEST option is to connect directly to the television as that method provides the least amount of signal loss and you only need one additional set of cables for audio to connect from the TV to the receiver instead of an additional set of component cables which are often more costly.

The receiver is going into "protect" mode. This means that a problem has been detected and the unit shut down to prevent further damage. Without seeing the unit and taking some internal measurements, it is difficult to provide a complete solution. Typically, the output transistors fail which can cause this. There are other possibilities too. I would suggest that you get a detailed repair estimate from a local shop. With that information, we may be able to walk you through the actual repair.

You might have to take a look into the unit, there could be some damage or a bad solder connection on the front left speaker connector at the circuit board, possibly also on any other component (power amp chip / transistors, internal connectors, etc.), also loose or broken wires or oxydized connector contacts inside the unit.

It could be something else as well, but i guess it's worth checking the above mentioned.

Hope you can fix it

Try making sure that the receiver has any video scale upconverting disabled. A lot of TVs also have upconverting to a native resolution higher than the input signal but 2 devices doing that procesing simultaneously can cause a device conflict. I think.

I assume you are looking to have sound from the television through the speakers that are connected to your receiver?

If that is the case then make sure you have connected the audio out from the television to the audio input for what might be labled monitor or TV/SAT. Then turn the volume on the televsion all the way up and switch the input on the receiver to TV/SAT.
