Samsung UN55B8500 Powers OFF/ON While Watching Program Material (HDMI Inputs). I've had this T.V. for about 8 months now, and it is a great TV, except for occasionally powering off/on- this is accompanied by the sound of a relay clicking. My parents have the exact same model and have not experienced any such problem. Is this the Capacitor issue I see related to on forums? If so, how easy is it to replace the capacitors in the power supply? I'm a bit intimidated to take the large flat panel apart to fix it myself. If the unit goes out outside of warranty, I will be doing just that. Thank you, in advance, for any assistance you may provide. Please don't recommend I contact SAMSUNG. I will do that in good time. I just want to know, from those who DO know, what the exact issue is. Thank you, Shane

Thank you, Electroman2! I will have a look at the capacitors on the power supply, if it goes out after the warranty. I'll be bending Samsung's ear soon, to see what sort of warranty service they will offer.

Hi Tumkyajano,
Thank you for your note. The tech who came to my house replaced two of the four boards in the unit, one of them being the power supply (the board with all the heat sinks and capacitors), and the other board was the main unit (which contains the tuner and most of the HDMI interfaces). The problem seemed to be better, but in the days after the replacement, the television persists in turning off on occasion. A discussion with the customer service representative with the local SAMSUNG- affiliated repair facility last week netted the opinion that the bezel along the bottom can be sometimes too tight against the actuation switches. A technician is due out to my house today to investigate the issue. Seems the bezel can be held too tightly by mounting screws in the back cover. Hi Tumkyajano, Thank you for your note.

Hows the tv so far? Mine was just fixed, both power and motherboards replaced. Hows the tv so far? Mine was just fixed, both power and motherboards replaced.
