Fairly new TV, a couple of yrs old, won't start and is stuck in a bootloop, not even getting past the full Samsung chime. I've seen this across the net on older Samsung TVs but not on one as recent as this. No obvious problems inside, no capacitors showing problems. Issue still present with the IR remote reciever all disconnected. Power board and Motherboard visually look fine. Any ideas? Even if someone could point me to a tech link or debug manual. Would be appreciated. TV was not cheap and I would have expected it to have gone well past the 12 month warranty before giving such a potential write-off problem.
