For example if a heatsink lifts off or a chip/part has become heat sensitive, both are inside out of user serviceable areas. Check purchase date, warranty and get estimates.
heya, I have a un46d6000sfxza samsung that will run for 5 1/2 minutes almost exactly. Then it will turn off and right back on and just repeats this cycle over and over. I updated the software but no help. Anyone have any ideas? thanx steve
