I disconnected all of my audio/video equipment to paint the wall behind it. I reconnected and had trouble with the AVR, but not the TV or DVD. Tech support suggested resetting the AVR (reinitializing), which puts it back to factory settings and then do a new setup. I no longer could use SVideo or any other connection for OSD, nor could I use the input button (IMode) to change from multi to PCM to DTS. The composite connection from my DVD to AVR no longer worked. Tech support now feels that the unit had a surge problem upon reconnecting and/or resetting and I have to send it in for repair. It is under warranty, but I have to pay shipping to the repair center and it will take about 2 weeks. Has anyone ever had this problem with a Denon? I do use a surge protector. Does anyone disagree why this happened?
