Many times per day, the TV will click, the screen go black and lose audio too (green light stays on). If I disconnect from power source and plug back in, it sounds like solenoid or something engaging or energizing and yellow light flashes green/amber a few times and then clicks again and goes amber. From there, I can turn it back on with an audible click, the screen will flash and 5-10 seconds later (most of the time) it will come back on. Frequently, it will go off again within a couple minutes, making it necessary to repeat the process. After 10 or so times of this, it will stay on awhle then do it again. Occaisionally, it won't click when connected back to power and must be disconnected again.
