Question about Yamaha HTR-5240 Receiver
My son gave me his Yamaha HTR-5240. I really like the sound but have a nagging problem with the unit. When playing DVD movies it will randomly switch completely off. Sometimes it only takes a few seconds after turning on the power, sometimes a few minutes. It happens most often during a loud audio outburst in the movie like a filmed explosion but it can be any sound even moderately loud. I lowered the amount of bass output from the subwoofer, but it continues to shut itself down. My son reported it did that for him too, but not nearly as bad as it is now.
The unit works fine with CDs. You can play them as loud as you want and never have a shutoff problem.
I reset the dynamic range which was set on "maximum" to "standard." That seemed to help for a while but the unit went back to doing the same thing. I fiddled back and forth with the impedance switch on the back of the amp but this didn't do much. I unplugged the unit from the wall for a few minutes thinking that maybe, as the manual says, the microchip may have been messed up with lightning, etc. After plugging it back in it did the same thing.
I have read the manual from cover to cover including the troubleshooting section and I swear I can't figure out what's going on.
I found this answer up above and it working. I check my speaker wires and fixed some and it has been working since then. I copied the answer below.

First i would strongly suggest that you review your wiring, since the problem occurred after those change , It might also be just coincidence. When you are playing something(music) go around and listen carefully to each of the speakers, check for muffled or distorted sound, that could indicate a speaker or wiring problem. Of course the problem could also be in the receiver. The protection circuit in your amplifier could be acting up(too sensitive), in that case you might need the help from a local repair tech.
Hope this will help Good luck
