Re: Auto off

that sounds like a problem with the HDMI which I assume you are using.Try a new HDMI cable.Otherwise there is a faulty interface on either the amp ot TV is my guess.

Onkyo standby

I have the same problem. Haven't exactly timed it, but at some point, my TX-SR309 always shuts off by itself when playing music from my iPhone connected in the front USB port. Hopefully someone has a solution for this.

I have an RXV-667. It is approximately one month old. It will turn itself off automatically after a few hours of use. The auto shut down feature is set for 8 hours and it has never been on that long. All...

But is it getting hot?

Generally speaking, an amp attempts to protect 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.

Just for GP, disable the auto shut down.

My receiver stays in standby mode and will not power up. It will turn off but will only turn on back to standby.

Unplug the unit from power and wait at least five minutes. Plug it back in and try it. If that does not work check your operating manual to see if there is a reset that can be performed. This would do a "factory reset" which would hopefully solve the problem. Good Luck!

Nakamichi TA2A gone dead

This unit needs an overhaul. There are defective capacitors and poor solder connections that need repair. I have done a number of these and the repair is straightforward.

Onkyo AV Receiver turning off - by its self.

The space you have provided should be enough. If this is a new unit and still under warranty, I would request warranty service. It sounds like the unit is entering protect mode. This may be due to heat or it could be because of a defect in the protect circuit. In any case, this should not happen that quickly.

Update this if not under warranty and I'll provide a list of diagnostic tests to help determine the problem.

The Kenwood VR517 home theater system wants to just turn itself off at about 5 minutes of being on. this just started happening this week.

If this unit stays on for 5 minutes, and it appears to be playing normal, a bad speaker could be the cause unless you are using speakers that are not compatible with this unit.

The specs on this unit are 100 watts per channel and require 8 ohm speakers. if you are using speakers that are 6 ohms or 4 ohms, you will overheat the unit quickly and it will shut down. It is not designed to use anything less than 4 ohm speakers.

If you are using the speakers this unit came with, or you know that the speakers are 8 ohms (it should be listed on the speaker where the wires plug in), go ahead to the next step.

The first thing to do is to unplug one speaker, it does not matter which one, just pick one to unplug from the back of the receiver or right at the speaker. If you unplug one right at the speaker, make sure that the speaker wires do not touch together or touch anything else, they must be insulated from anything metal or conductive.

After one speaker is unplugged, turn the unit back on and let it play normally the way it was when it shut down after five minutes. If the unit continues to play for a long time, at least 30 minutes or more and does not shut down on its own, you have just found the culprit causing your problem. Some speakers may sound like they are OK, but still can cause a problem.

If the unit shuts down again after five minutes like before, go ahead and plug that speaker back in and do the same thing with one of the other speakers.

Continue this process until you have isolated one speaker as being the problem.

If you go thru the entire process and it still shuts down, you may have an internal amplifier problem. It can be something as simple as some heat stressed solder joints that need to be reflowed, or it could be a bad amp IC. This unit uses 3 different amp IC's and it could be any one of them or a component in the amp circuit. Sometimes it can even be a power supply failure. In any case, if the above steps do not work, you need to take it in and be serviced. There are no other end user options to perform.

I hope this helps with your problem, if you need more help just ask.

Receiver shuts down and will not turn back on untill you unplug and plug back in

Nope. sorry to burst your bubble but your problem is pretty common on this unit. Its bad capacitors in the power supply and probably not worth repairing in a repair shop. since this is a solid state reciver, there are no user replaceable parts inside.

Shutdown protection? HELP please

All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.

Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.

Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.

Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.

Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.
