Question about Yamaha RX-V3000 Receiver
I have a Yamaha RXV3000 receiver that will work for a few months with no issues and then when powered on it shuts off like it is in protection mode or something similar. I have unhooked all connections and have reconnected. I thought it might be a short in my main speakers but I have since replaced and it worked for about 3 months and started clipping off. I have taken the unit to the repair center twice and they can not replicate the issue which tells me it is probably not the unit but somewhere in my connections. If I disconnect everything, the unit will not operate for a number of days but then it will start working with no issues. I have switched speaker wires. Currently, I only have mains and center connected to the unit. Can connections such as video be causing a short of some type? I have another Yamaha receiver that is older and connected it to the sames speaker set and it worked without failure for a couple of months. This very frustrating and any help would be very much appreciated. Turn on then It turns back off right away, but this is an intermittant problem
Most, but not all of the voltage regulators are cooled by the same heat sink
that the output transistors are attached to and get overheated when you crank up the volume. Although this unit has a cooling fan, after some time the heat sink gets HOT and will age these parts. There are also a group of three current limit/ voltage drop resistors supplying one regulator that will give up too. This is not for most DIY folks. Repairs are available in certain parts of the country. I know of one you can ship the unit to and get it fixed like I did.

I also had the very same problem.....I followed the instructed already posted indicating that it was a speaker problem....Instead of disconnecting all speakers at once, I went pair by pair.....and tried to turn it on and see if unit then would stayed on...not really...I continued with the same process....until I got to the last set of speakers....to no avail...
Eureka!.....a few minutes, say 5 or 10.....I turned on the unit and stayed ON!! ! ! ! ! !
Than I re-connected all speakers......and the unit is working fine.
I was at the point of purchasing a new one........to this day I do not have a clue of what caused the unit to go into "protective mode".....
Folks, try this route......and it worked for me....It was a matter of luck...perhaps...I do not know.
