Problem with Yamaha rx-v450 amp

Yes i have some thought but why did you check your speakers for your problem ? This is confusing. Does it turn on at all or not ? itf the unit doesn`t turn on then it is not the speakers. What all did you check on this unit. Did you atleast check for bad solder connections ? I have the schematic but I am not sure if you know how to read it to undersatnd it to help you to locate your problem. Please give us some more detail besides just checking speakers.

Service manuals are available from Yamaha for about $18, but unless you are trained or have a lot of experience on these units, they can be a bear for even a good tech. Could be a leaky backup cap, which have been known to cause problems on some Yamaha receivers. Needs some real diagnosis. I'd look for a shop that is a Yamaha ASC or at least does a lot of Yamaha service.

Speakers would not likely cause intermittent power on. Curious, though, how did you "check" the speakers?

They've had some problems with the power-on relay in these...

The user manual indicated that the unit will switch off if there are faulty speakers,.I checked the speaker wiring looking for shorts. By investigating on the net I now assume that the unit will turn on for a second or two before it turns off.

I have not gone further until I get some circuits, no sense probing around in the dark and maybe causing a further problem.

Hi

I have the exact same problem with a Yamaha RX-V1400. Unit shuts-off after a few minutes even with no sources or ouputs connected. I did post about it here awhile ago but received no reply, so in the meantime I sent it to the local Yamaha Service and it has been there for 4 months. They now say the EPROM has lost configuration and they are waiting for a new one. I suspect they have stuffed it up as I don't think the EPROM could have been the cause of this problem. If you or anyone finds the cause of cause please let me know. And IF mine ever gets repaired I will let you know.

Who did you send it to? Yamaha would have likely take some action by now if there was that kind of delay for parts. You need to call Yamaha customer service. Where is your dealer in all of this?

Hi Leonard

I have e-mailed Yamaha through the customer service section on their EU site MANY times but received no reply. The dealer I have to deal with is Videoacustica in Portugal. When the unit first developed the fault it was still under warranty but Videoacustica said that they would not repair it under warranty as I did not purchase it from them. I purchased the unit in Germany but as per EU trade law the warranty should be valid in Portugal aswell. Not so ?

Anyway....very dissapointed with Yamaha for not replying to my e-mails and I don't know who else to call in Europe regarding this matter. Maybe someone here can help ? !

Cheers

Is their a Consumer Protection or Fair Trading body in your local government? A complaint about the lack of reasonable service might get someone off their backside. Perhaps a warning that you are contemplating such an action might get the repair accomplished.

No experience with Yamaha outside the US. Here they are very customer oriented. They will not, however, support products from another country.

I would go back to the vendor in germany.
