Why does receiver click

When using the analog input on the front, the audio doesnt drop. But the clicking is quite loud anyway. Looks like some discoloration going on there. Yeah, I saw that as well. But like the two patches near the center of photo 2, I think it is just some odd discoloration as none of the local components show any visual signs of heat damage and the solder points all look solid.

I havent removed any of them to test, though. Is it possible that this could just be a faulty relay - instead of bad cap or whatever is triggering the relay? I havent been able to pinpoint which relay it is yet since its now being a PITA and only doing its thing when I'm out of the room.

But, Im pretty sure its either K1 or K2 photo 2. I was going to try to clean it up, but they dont seem to have a removable cover like many do unless the latches are on the bottom?

And since K1 seems to control the primary speakers, is it possible that this could be caused by a speaker load issue? Guess I'll verify each line is 8 ohm. I have a Kenwood vr For example, faulty connections could be causing the speakers to cut in and out when relays are switched within the AVR. Check your connections on the back of your AVR, giving them a little wiggle.

If this has any effect on the speakers, then it can be worth investigating in a bit more detail. Even a single stray wire can cause a short, which can cause the speakers to drop out.

If your wiring is held in place with banana clips, then take these off and check the wires themselves. Reconnecting the speaker wires could also make a difference, so taking them off helps in several ways. It could also be an idea to take the banana clips off and see if this makes a difference to the sound.

The circuitry inside an AVR is relatively sensitive, which can be both a benefit and a problem. The clicks and ticks could be caused by something as simple as the relay being stuck. All you need to do is lift your receiver up at the front by a small amount and then drop it. You might be horrified by this idea, but I only mean for you to drop it by a few millimeters. Doing this can jog the relay out of place and get it working again.

Not only have I tried this myself with success, but I know plenty of other people who found this worked. Develop and improve products. List of Partners vendors. Gary Altunian.

The result: relay clicking on and off continuously.

How can you tell which is which? Easy: look at the display. If the display turns off when the relay clicks off, it means that the electronics have reset due to low voltage. If the display stays steady, it means the protection circuit has tripped. The former is probably due to a bad capacitor. The latter is probably due to a short circuit. The capacitor is likely easy to identify and replace if you know what you're looking at when you open the chassis.
