Question about Yamaha HTR-5650 Receiver
My Yamaha receiver used to be fine, until sometime ago when it started turning off after a while and signalling "check SP wires". I check all wiring very carefully and even changed the cables. but even without any speakers connected to the receiver it turns off in a matter of a second after switching it on. Anybody knows what to do about that?
There is any short circuit either at its speaker end or its amp output circuit. Just disconnect all of the speaker wires, and turn ON the set, If the set behaves so, as it was, make sure that the amp output circuit has the fault. Is this the case, contact any service technician.
If the set switches On and stays as it is, after disconnecting all the speaker wires out from it, switch of the set, and connect the speakers one by one at a time, switch on the set, and check, which speaker connection causes it to a halt. Thus you can identify the faulty speaker. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts.

SOURCE: check sp wires?
Your problem most likly is not because of dust. Its a bad connection in the amp section or the protection circuit, or the speakers them self have a problem. There could also be a componet problem. Unless you know how to troubleshoot solid state electronics,you should take the unit in to be serviced. It would most likly cost more then its worth to repair. A unit this old is u replaced at this point. Good Luck

Your Yamaha is going into protection model.
This mostly happens when:
1). There is rise of internal temperature.
2).Core wires of the speakers are touching each other or a core wire is sticking out of the terminal and touching the set's rear panel or the speaker itself has a problem.
3). Speakers with an impedance other than specified are being used.
4). the set is damamged or has bad solder / dry solder connection .
Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Rewire if necessary..
Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.
If everything else seems all right and still your receiver shut down then it possible that
1).there are bad connections on the main board that are set in.
This would generally happen if the system is slighly old or have dry solder. This should be a simple repair that will not require parts. If you can solder, you will be able to repair this yourself. I could guide you a bit. If not, then a local service center will change the local labor rate.
2). Some transistors have blown on the output power board:
This will require little bit of more electronic knowledge.
I suggest if your set is still under warranty, then please take it to Yamaha.
Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further.
Thanks for using FixYa!

SOURCE: the same..
Your unit took a power spike or a brown out; big dip in power then a surge. Yamaha's receivers are pretty solid when it comes to power supply's! it takes alot to zap em! If that's the case, it's about a 275 dollar repair. They will replace main transistors and caps. If you don't have a serious Home Theater Surge/Conditioner (not a power strip) get one! any receiver with today's spec's will be toast!. If you need some guidance on receiver's or surge, post a comment and I can help you out. Sorry for the bad luck!
