Ade up,my second ampli yamaha rx series shut down after a couple of seconds and my warranty just terminated. Regarding numerous issues with those ampli I consider yamaha organise a global rip off . Do you know any association ready to go to court to stop such gangster company.
Maybe the problem is with your speakers. Shorted speakers or speakers that are being over-driven can cause the receiver to shut down and possibly be damaged.
Testimonial: "Speaker tested ok .According a french forum problem is coming from weak tension caused by cheap cheap components provided by yamaha . It s a shame. thanks a lot for your help"

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.

it is your protection circuit working, preventing the unit from any further damage to circuitry. you can check first your speaker cabling for any short connections, possibly red/black terminal wires got entangled. if all ok then try removing all speakers then turn on the amp. if still does the same thing turning off then you have a problem with the amp output stage, shorted power output transistrs/driver probably. if the unit turns on normal without the speakers then you must have one or both of your speakers busted. by the way this amp is multi channel, after removing ALL the speakers connected, and does not turn off anymore, put the speakers back one by one and observe if the unit with turn off and on which set of speakers. otherwise if still trips even without the speakers, it is your amplifier that is deffeective, any of the five channels, main, rear,center. let me know result so i can guide you on how you can get it repaired and what will be the extent of damage in case.

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.

Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.
