Thanks Bob!

The problem is that a customer contacted me stating his unit went dead
after an attempt to update the OS - which is quite odd. According to
him, he tried everything to resurected it. But the unit stay dead -
won't power up at all.

Of course, there are the usual suspects like the power adaptor, the
power socket, a capacitor in the power supply area.

That's why I wanted the service manual to study it a bit and maybe
pinpoint the origin of the problem. To my experience, no synths I
worked on mysteriously died from an OS update (which was supposedly
downloaded from the Yamaha website).
