need Help-Yamaha AVR protection issue

[deadpool]

Sounds like the Yamaha service people no longer troubleshoot, only change boards until it works. That isn't what I would call "service". Any idiot could do this. It looks more like a quote for insurance, they quote high so insurance would replace the receiver with a new unit.

spirovious, what equipment do you have?

we trouble shoot to component level in Melbourne🙂🙂😎

Ditto in Canada.

Called a technician today and he said most of issue can be corrosion and its common with Yamaha AVR.I guess its not only issue.

 

[anatech]

That is something we don't see in the northern latitudes.

I did clean PCB,but no result.
I will take to local service center soon.

I took it to the technician,but Yamaha did not shut down even after 40mins. So brought back and will check home again.Very strange 🙂.

It seems it doesn't like you.

Just a correction.Today it was 252V. Can that be an issue?

Yes, it is possible. Take the receiver back in and have them run it at higher voltage. Most shops will have a variable AC transformer which will allow them to run equipment at voltages off what is accepted as the normal line voltage.
