Hello, I got a ONKYO TX-SR373 from neighbor with amplifier damaged. Output transistor of FR channel shorted. My neighbor report that it starting to distorted then blew up. I managed to fix the amplifier (maybe?) by diagnostic every parts of that channel, replace related parts, re-check again but unit still refuse to turn on. Relay clicked (haven't press anything, seem to be powering on by itself) but nothing happen.
I do further re-checking, voltage at all rail is still fine fine. Unplug amplifier from unit won't help.
Note : Relay will click after 2-3 second of plug the unit even I haven't press any button. Front display always blank, reset function won't work.
I never own Onkyo product and don't really sure if it normal that unit turn on by itself for doing something or not. I haven't leave it plug in for long time, I'm aware of it might get more damage.
