I have had my Pioneer Elite PRO-710 for almost a year now and have really enjoyed it. For the past week or so I have had a problem in that it suddenly clicks off and I have to turn it back on using the manual power switch on the front panel. It sometimes takes me a time or two to get it to come back on, but so far it has worked. I am thinking that this must have something to do with the power supply or something. Has anyone else had this kind of problem?
