You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies. Good Luck

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

Check out the fixYa solution for the Samsung LNS4051D- it sounds like the same problem. Defective capacitors. You may need different part though. We just fixed my mom's LNS4051D with that problem. I have the LNT4665 and although it hasn't failed yet, I am tempted to get some capacitors just in case.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?
