Good day folks. Last time I needed some help with an amplifier, people here were very nice and keen to help, so in hopes you can help me once again, here goes: I have this Pioneer VSX-920 receiver which shuts off after about 1 minute after startup. The display comes on, everything works, but the set turns off after said time. I must admit I haven't knocked the cover off to have a look inside and take any measurements, so for now the discussion is going to be rather generic about what could actually cause this. Failed output transistor ? Bad capacitor ? Bad main board (this was my colleagues' suggestion, after encountering a similar unit in the past) ? I've linked the service manual here, since it's too big to upload, but haven't opened the unit yet like I said. Any thoughts from people more vexed in the field of audio amps would be greatly appreciated (I'm more of a TV guy and only know some basics about amps)...perhaps someone knows this to be a common fault with Pioneers or something. Cheers and thanks.
