This past Friday and Saturday, my VSX48 started changing/jumping through presets out of the blue. Right in the middle of the band paying a song... BOTH NIGHTS! I thought it may have gotten too hot, so I put a fan blowing into the back of the rack Saturday and it still happened. I had to stop the show entirely, unplug the unit, wait a few seconds, start it back up, and reload my preset.
I cannot afford to go through that again. Does anyone know what the issue might be?
