Re: Sony STR-KM7 Not Powering On
UPDATE.................................
I shorted out the relay RY901 output terminals and it works.
There must be a problem with the signal to the base of transistor Q901 which drives the relay coil. I couldn't be bothered to find out what it was.
This solution may help mojos911...
