My Pioneer receiver has developed a problem where the functions [any of them] will not work either on the unit or remote. I cannot turn it on and off or use any functions. The only way I get it to work is to 'reboot' by turning off the main power switch. Then it works fine for about a week then I need to again 'reboot'. The good thing is that I bought an extended warranty. The bad thing is that I bought it from Tweeters! Very confused. Any ideas?
