For the first time since I set up my system (june 04), i tried to go back to the osd menu of my AVR-200, but the screen was flickering like a bad cable station. Looking for suggestions to troubleshoot this before i bring it back to the dealer. Right now its hooked up via composite cable to my television. I tried two different composite cables and two different composite inputs on the television, with no luck. Any suggestions would be appreciated.
