Question TV shuts off intermittently and will not respond to remote or buttons on tv. Power light comes back on, and the tv will show the last channel window but otherwise black screen. It requires unplugging for several minutes to reset, then works ok until it happens again, maybe a day, or week or month later. No storms or malfunctions of other electrical items in house.
Answer It is most certainly an errant power supply or some subsection of the main power supply. It generally requires replacement of a rectifier, zener or some part of the regulating system. Cost of repair is likely to be in the range of $200 if you can lug it in to the shop; more if they must come to your residence.
