My receiver suddenly started to shut off seconds after I turned it on. It was working fine one day and then suddenly developed this problem. I really hate the thought of undoing all my connections. Any miracle ideas?
I have had mine for about three years now and this problem has occured three times now. Tap Electronics in Buena Park California is the real deal. They have fixed mine twice, and now that it has happened again they no doubt can do it again. The part number they replaced is UR267470. The part description is C.EL 47uF/50V. These units seem to be a little too delicate for me.
I've been having the same problem for 3 months. Checked connections, sent unit out for repair (3x), contacted Yamaha (no help at all) and still the same problem. I've spent over $350 in repairs and I'm very frustrated. I think I'm going to just buy a new receiver (not Yamaha).

Yamaha CorporationRX-V540. Discontinued. Natural Sound Home Theater Receiver. 0.0. (No reviews) ...The RX-V540 is a full-featured home theater receiver ready for all formats. .... their favorite stations or to have musical genres, such as all the jazz stations,
Feb 13, 2015 - no sound on yamaha rx-530 stereo fm receiver nothing,just no soundcomming out of speakers ... Does your TV have any audio outputs such as RCA perhaps? .... Suddenly no sound is coming from my speakers except for my subwoofer. On certain settings some of the speakers work but not all of them.
It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.
When it shuts off, does it display anything on the front like "ck speakers" you could have a shorted wire or bad speaker. Sounds more likely than a bad receiver. Yamaha is pretty bulletproof in "self preservation" circuitry! about the only thing that takes them out is lightning and major power surges. I have been selling and installing Yamaha receivers since 1995 and have only ever seen one with a problem that was unrelated to power. and I've done hundreds. If your not using HDMI, and the Video portion of the receiver, I would definately keep the unit $ 1500.00 is no cheap receiver. Try disconnecting the speakers, then turn on the unit with a source connected like cable/sat/fios on then crank the vol and let it set, if it cuts out, yes you've got a problem internally, however, I would stronly suggest metering all of the speakers and wires for shorts. There is an internal fuse as well right near the power cord, you have to pop the top to get to it, If you have a multimeter check the fuse with resistance tone. If you get tone, you have a good fuse if not If you need to replace it. They can be found at Radio Shack etc. If the fuse is OK, chances are you've got bad transistor(s) and needs to go to service. Repair should be under 200, well worth it. If you have further questions, post a comment and I will get back to you ASAP. Hope this helps
Seems like you have a shorted output channel, remove all your speaker connections and try again, if the problem persist, good chances are that you need to replace a couple of power transistors, let me know if you need more help, I've fixed some Yamaha amplifiers with this problem
