As found in...Pioneer...type of product and model number?...but will probably be device specific customs to the manuf. If U get data back in time, I will try to really-search for U in the LRC on Sat.

oops... model is
VSX-0457 A/V multi channel reciever.<p>when you turn the unit on the message
POWER UNIT OFF shows on display.. i figgured one of the amp chips was blown , since they are hybrid chips,, hard to test them,,, i took all 3 out. and repowered unit...safty relays kicked in ok this time and no POWER UNIT OFF message showed this time... just normal display... so i am sure one of the amps is the problem,,

I can't remember where at all, but I've found an internet resource for those types of chips before (multichannel amp, STRXXXXX). I serviced a car audio cd receiver that had some chip like that and needed a new one (casing was cracked open, leads literally torn in half).<p>Anyway, I'll search around and try to find it again.
