What was the routine for the factory reset that you did? Your manual says: "To reset the AV receiver/AV amplifier to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] but-ton. “Clear” will appear on the display and the AV receiver/AV amplifier will enter Standby mode. "
My first step would be a soft reset (unplug for a while) and then a microprocessor/factory reset....maybe several resets.
