Shucks – the TV Went Out
This morning I turned on the TV in the living room and there was a dark region about 40% of the screen right in the middle of the display. Now this has been a good TV for me for about 10 years, no problems at all, but this kind of thing usually means replacement, because at 70", the replacement cost is about the same as the repair cost.
I'll give it a few days, but if it doesn't clear up with some power-cycling and cable checks, then it's a goner, and I need to be looking for a replacement.
