So far this is my experience with my 2012 Plasma TV that had a main
board fail. Excellent TV until it decided not to completely power up
one day. I may amend this post if they come through with a
partial(depreciated) refund after "reviewing" my case for close to 2
weeks.
willand, i had what may be the same power issue with my samsung tv--there's a diy fix that even i was able to do involving replacing $.50 caps--google it
