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.

SOURCE: yamaha rx-v461 not working

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.

My Yamaha RX-V563 receiver displays "Check Speaker


Look closely at the rear connector panel of the receiver and look for pieces of stray strand wire that may be touching the speaker A binding post and the receiver chassis. If you are not using strand wire connection to the binding post then check whatever connector type you are using such as banana plug or spade plug for breakage or corrosion, the same goes for the speaker cable itself which isn't always so easy to detect. A few broken strands can cause a problem.
If it is clean, turn off the receiver and disconnect the speaker cable. Check the binding post for tightness; if you can wiggle it then it is broken and needs to be replaced.

My Yamaha rx-v663 turns on for a few seconds then shuts off within 2-3 seconds. The first time the unit shut off was after it had been on for a while. I turned it on and it worked fine a little later. When...


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 '*****'. 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 another possible root cause for intermittent shutdown.
