Dear friends
Good day !
A friend of mine brought in a YAMAHA RX-V459 AV Receiver - amplifier.
He says that it just stopped working.
When i plug it in and press power button i can hear the input relay clicking and a few sec's later it clicks again and the device stays off.
I remember exactly the same symptom on an other yamaha audio amplifier and the problem was a large poly cap at the input and also the jack connecting the psu pcb with the rest circuit. but this is not the cace with RX-V459. i tried to find something on the net but came up empty. I will look for the service mnual to study the psu circuit to see what drives the relay...
Any suggestions ?
