    ive also unplugged the unit from the wall for about 10 mins, then switched it back on and it was fine, but if i turn it off, then on again, it goes back to the switching off after 2 secs thing.

Return unit to place of purchase, this is clearly a manufacture defect. The warranty will cover full replacement, do not allow them to attempt repair on the current item because you will be back and forth until warranty runs out.

I set a fan on top of my unit just so we can watch movies, really it works. It needs to be a small 8 or 10 inch fan with 3 speed control, the louder you turn the surround sound up the higher the fan needs to go.

Does the reciever have separate speaker switches?
Try turning off the speakers and turning on the amp.
If it doesnt have speaker switches , make sure ALL the speakers are connected at both ends and try turning on the amp again.

SOURCE: Yamaha RX-V1500 Shuts down after 2 seconds

This set is getting old and is in the Archives section of the Yamaha consumer guide area. But, you can still download the owners manual if you need one. If it is going into protection mode even when there are no speakers connected OR when the sound level is very, very low or zero it is not good news. Yes, unplugging the line cord will cause the protection system to reset itself. But, if it shuts itself off again soon after rebooting it is a sign of bad grease in the output stages -- in all probability. Let me explain: The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set). That is the most common cause of your symptoms. However, there are several other possibilities, but I give this explanation a 90% probability based on my experience.

SOURCE: 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.

SOURCE: Yamaha RX-V995 receiver turns on & then powers off 2 seconds late

I suggest you run self diag.  press [FM/AM] key + [Input mode] key and press the [power/standby] switch.

ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink

you'll likely have to measure the resistances of the output FETs to find a short,

Had same problem. Display would read, "Check Speaker Wires". Rear speakers were shorted by a carpet nail. Works fine now.

Problem with yamaha rx-c2092


Hi, try to unplug this unit from the wall for a minute or so, It may just need reset. If it still does this I would say that you have a loose wire inside where the power supply is. I would not recommend working on this unless you are computer savvy.

Get another receiver! I had the same problem and had the power supply replaced $250 and after 3 months it started doing the same thing.  I just purchased a Pinoeer Elite VSX 90TXV.
