Hi, everybody! My 5 month-old Panny just has started behaving strangely. After being on for anywhere b/w 30 min. and 2 hours it switches itself off, the red standby light blinking. I cannot turn it back on with the remote- have to manually switch the power completely off and then on. And after that it's working just fine. The only recent change to my system, after which I've began experiencing this problem, is the addition of Harmony SST 768 universal remote. If anybody here has ever experienced similar problem, please help, it'll be greatly appreciated. Regards.
