I have a Hatachi 60UX54B and if I leave it unplugged for a few minutes & then plug back in the set will power up for a few minutes then shut down and will not power up again. It seems that when the unit warms up the the power drop out.
Thanks in advance,

Re: Will not stay powered on
Does the convergence look OK before it goes out/ Have you opened the set to see if there is any liquid or any staining on the printed circuit boards right under the picture tubes? This set is very common for the CRT coolant to drip out of the tubes and fall onto the printed circuit board. good Luck

Power cycle your TV by unplugging it and leaving it for a few minutes. Plug it back in and turn it on. Restore settings back to factory defaults. If everything else fails, then I would recommend pursuing repairs.
Try power cycling the TV. To do so, unplug everything from the back of it, power off the TV and unplug it from the wall. Leave it unplugged for a few minutes, and then re-connect and plug the TV back into the wall. Turn it on and reset any system setting changes back to factory defaults. If the problem(s) still exist(s), then I would recommend scheduling repair service.
Unplug your player from the power supply (do not just set it to standby). Leave the player for a few minutes. Plug your player back into the power supply and switch on the machine. This should unblock it.
I've had the same issue although I don't unplug everything. I turn it off and then unplug it from the wall for 10 seconds then plug it back in. Seems ok after that. Has happened 4 or 5 times over the 10 years I've owned it.

then it points to 1 reason:
the screen is heating up and the automatic circuit shuts it down...
try locating it some cooler place or put a vent behind it...
see if it does any help
