If "Digital" sign blink on front panel, it means DSP do no start properly. If DSP do not start, main UC mute audio. Change IC, AT49LV002-70TC (IC 817 ) at DSP board (Denon P/N: 262 3010 006).

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.

SOURCE: I have a Aiwa Stereo Receiver Av-D58. The sound

If I remember this model correctly, there is only 1 direct input. The remainder of the inputs are bufferred through a switching IC. It is likely that this IC is defective. Are there any other symptoms at all?

Thanks,
Dan

Onkyo AV- SR503 WHY DOES IT MAKE CLICK SOUND WHEN I PRESS POWER BUTTON. THEN IT CLICK AGAIN AND TURNS OFF


There are a couple of possbilities here:
1. Make sure you have a good power connection that is not overloaded. If you are using a surge protector, try plugging the amp right into the wall to see if that makes a difference.
2. check all your speaker connections to make sure you do not have a short. The amp may be shutting down to prevent damage.
3. If you cannot find a problem there, what you may want to do is disconnect all speakers and try to turn the unit on. If it starts normally then you know for sure you have a speaker problem.
4 If above does not resolve problem, then unplug all inputs and try turning it on.
If it still does not come on then likey you have a hard fault with the amp and it will require service.

Cambridge Audio Azur 640R AV Recorder won't switch off


Sounds like the unit is victim of a power surge. The power control board is probably damaged. You will be better off replacing the amp as having it repaired will cost more than replacing it.

Denon 1312 makes clicking sound will not turn on


If the front display does not light up at all when the press the power button, it is usually either the main power fuse or the power transformer. If the fuse is blowing, that usually means a short in the amp section.

My Sony STR-DG500 wont turn on just clicks once and nothing.


Sounds like faulty psu (pwer suply unit) Amp is going into protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not psu, sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If on, connect speakers and av cables one by one and test each one on its own until amp switches off, Investigate from there were problem is. Make sure speakerwires is not shorting out.

No Sound


when the amp is turned on does the unit make a clicking sound a few seconds after the display lights up.

if not the amp's is not happy with it's power or could have a speaker short. Check the display for a fault warning.

Otherwise check you speaker connections.
confirm that and A and B main speaker buttons are correct.

Try some headphones, if you get sound out of the headphone things might not be too bad, if nothing is output remove all your cables and try again.

Yes I know that can be nasty, so label all the cables first.

Sudden failure to power up


I've had this happen a number of times with my receiver. This trick from the Troubleshooting guide in the owner's manual usually does the trick: To reset If an unusual condition in the display window or malfunction occurs, reset the unit as follows. 1 Press the POWER button to turn off the power. 2 Press the POWER button while pressing the ENTER button. Everything stored in memory after purchase is canceled. If the power cannot be turned off in step 1 because of a malfunction, reset by disconnecting the AC cord and carry out step 2.
