Similar situation as previously described with the Denon AVR-1508, but mine will shut off after about 10-12 minutes the first time around and then ~2 minutes after it is turned off and then back on. Unit...

Most new receivers have a fan on the back, if you have one check to make sure it is working, most won't activate until the unit gets warm, other issues are bad solder connections on the audio outputs causing intermittent shutdown, as a final inspection check speaker connections to the receiver and speakers.

Hi im wondering what the cause of overheating in CYRUS III Amp!! Anybody had the same issue, after using a high volume for 30 minutes or so, then the protection relay operates!! Best Regards, Mac

Protection mode is there to prevent your receiver from overheating to the point of failure. Try this. Make sure it is ventilated real well. Put it by itself. Don't stack anything on top of it. Even if it has a fan I us a little fan behind my receiver to circulate that warm air off of it. This works real well. Make sure your receiver is setting on a nice hard surface too. Not carpet or anything shaggy like that. Receivers and amplifiers will go into protect if they are rode real hard. Keeping it as cool as you can will minimize this. You can also turn the bass and or gain down on it a bit every now and again to help it cool a little bit. That receiver has final transistors in it that get war as power increases along with the time it is increased. Keep it cool and your it will stay out of protection mode.

My Tchnics Sa-Da10 shuts down on what appears to

Ahh technics. Technics always had overheating problems, trust me. Every since they started, their amps would get so hot they would hurt to touch. The reason the fan is not coming on seams to be something inside the circuit board. I'm sure that technics could fix this. If the fan works out of the receiver, then it must not be the fan. ;P

I would maybe get a computer fan, and just put it on top of the receiver and turn it on, or send it in for fixing. Also, do you have to crank the volume to get the speakers to play at your volume, and does the impeadence match the receiver. Because you may be pushing the receiver too hard.

Denon avr-1706 receiver just shuts off

This sounds like the amps protector circuit has been activated due to thermal overload. switch it off for an hour or more to let it cool down, make sure your spkrs are connected properly, don't parallel. Try using a fan on the unit to get that heat away. Get a techie friend to give the insides a once over, and clear away any dust that has built up.

hope this is of some help,
Cheers Kimbo.

When turning the volume up to the mid level spot on the dial the power on my yamaha rx-v793 clicks off. Apon turning the power back on,the unit will stay on as along as the volume is below the mid range....

Check your speaker connections, the unit is shorting out. Best way to make sure it's not the receiver is to disconnect all speakers then turn on your receiver,turn on a source like cable or dvd and turn up the volume on the receiver. If it stays on, you know it's not a problem with the receiver.

Now to find the problem; re connect speakers one by one, each time, turn on the receiver and turn up the volume, when you get to the wire causing the problem, it will shut off. At this point, disconnect the speaker wire at the speaker causing the problem to make sure it's not the wire itself. Make sure the loose wires do not touch each other as this will cause the unit to short or worse! If it still plays, then look at the speakers internal connections if possible. Look for the obvious, burn marks on a crossover or wires touching, if you find none, use a multimeter if you know how to read one and set it to resistance. If it reads 1... you've got a bad voice coil and the speaker needs to be replaced. Most often, however, is that a partial part of a speaker wire braid has touched the other. + to - and does not have enough of a load to short out until you turn up the volume. The other scenerio is if your wiring was "pre-wired" in your home for surround and there is a nail or screw in the wire and doing the same thing. If you still have issues beyond this, post a comment and I will help some more. Hope this helps

Receiver frying noise

I have the same unit and discovered there's 2 cooling fans inside.
one is not working at all and the other is turning very slow.
With that said I'd open the cover and see if it's the fans.

Technics receiver SA AX540 overheating

is the fan turning on? many models like these have a cooling system (fan) that kicks up when the volume is turned to a certain level. if your fan has never been on, then chances are some of your soldering points have shifted or gotten a little messed up over time from the heating/cooling effect. this model runs extremely hot especially right where the vent is on the top of the cabinet. make sure that it is not in a shelf or enclosed area. dont stack other items on top of it. use an external device to control the volume so that you can have the receiver volume at a fixed level where the fan will turn on. if your sound still doesnt work, you should consider buying a new receiver or try your local craigslists forum. make sure if you buy a new one, that it is a more expensive model from a brand like sony and check the model online for known problems. stores like best buy offer extended warranties on most of their products which are very wise investments. good luck sinbad
