Anyone have a schematic for a Sony STR-AV920?

chipper · 9th March 2011, 01:45 AM

Hello, I need a scematic for this receiver or perhaps can someone help me figure out why it won't turn on? It was givin to me for free kind of tooken apart. Theres some parts missing (output transistors). It won't turn on, when you press the power button you can hear the relays engage on but nothing won't turn on for the screen

. Some leds turn on like DRLC/POWER light turns on and some other small leds turn on but nothing for the display. If someone can point me where to check so i can see why the display won't turn on or help me get a schematic i'd apreciate it

It's a pretty heavy receiver also has 63 volt caps so it must be pretty powerful. Has anyone dealt with one of these? Are they good?? Thanks

I take it no one has any knowledge on these receivers or stereo amplifier repair? Atleast a schematic would be great.
