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

Reset instructions

If you are trying to power cycle (reset) your TV, then power it off, unplug everything from the back of it, and unplug the TV from the wall for a few minutes. After a few minutes, plug everything back in, and power on the TV. You can also reset any system changes by restoring them back to factory default.

If the problem still exists, then I would recommend setting up repair service.

House breaker triped I reset it but now my Hatachi 57TWX2OB has no picture or sound but power light comes on on front panel

hi, you might get lucky and have a locked up micro, un-plug the ac cord for 1 minute and then plug back in, this will do a hard, set-re-set of your tv. If still dead then power supply has been damaged and you`ll need a tv tech to diagnose it, good luck, video-tek

Hitachi 60" picture flashes on and off.

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.
