My 55" Roku Tv started cutting on and off by it self last night. Its a highsense tv so when its on the screen that appears is the screen that comes on when you cut the tv on and then 5 seconds later it goes black then 2 seconds latervit cuts back on. It dosent stay on long enough to get to settings ive also tried unplugging it waiting a hour then plugging it back up and its still doing the same thing. Ive tried plugging it into a different outlet and its still doing the same thing. Ive tried to do a factory reset and it wont reset so at this point what do i do
