Optimus is Radio Shack. Good luck. Parts and/or Manual. Not much help around here. -Ed- Ed Gaidies Tel-Tek Electronics Ontario-Canada teltek3@xxxxxxxxxxxx -----Original Message----- From: techassist-bounce@xxxxxxxxxxxxx [mailto:techassist-bounce@xxxxxxxxxxxxx] On Behalf Of CGRIFF4000@xxxxxxx Sent: Sunday, November 30, 2003 1:58 PM To: techassist@xxxxxxxxxxxxx Subject: [TechAssist] Optimus STA-900 Receiver Protection light on, No sound I don't work on audio equipment very often, so this may be an easy fix for some of you. I have an Optimus STA-900 Receiver with no sound, protection light stays on. If I trip the relay, I do get sound. The relay is good. The output transistors check out fine. A schematic would be helpful if anyone has it.
