POWER DOES NOT STAY ON...PLZ HELP

There's a problem with the power supply or another board drawing too much power from it. It needs a service tech to determine which.

you have a bad power supply

Unplug the tv and leave it unplugged for a couple hours. Plug tv back in press reset button. TV led may flash for a day but should come on. I did this last night to mine and it came on at 11am today.

Power converter board it dead.
Need to be replace.

Could be h.v. splitter.pull the lead coming from the flyback that enters into the h.v.splittter. Put lead in a quart jar and turn the set on and see if you hear a hissing sound, if you don't see a blue arch also. If set stays on then h.v.splitter is bad.

What a great tv this is Mitsubishi did a fine job making this one, but......only an authorized mitsubishi servicer should repair it. This set records diagnostic led codes that the technician receives to help determine where the problem might be, not the problem, but in which circuit it might be. The one thing to try is, unplug the tv , let it set for a minute, plug it back in , turn it on and hope it reset the micro. Next , call for mits. service.

Sounds like what happened to my hitachi. Power voltage regulator on the main pwr board.

Seems to be the power button is stuck on the tv itself

Hello nicolastran,

I gave this advice to someone with this same problem so here it is again:

It sounds like your shutdown circuit is being activated. This is due to excess current being drawn. This usually happens in the High Voltage section of the TV or one of the deflection stages. Due to the nature of this problem I would suggest that you take it to a local TV repair shop or have a TV repair person come out and take a look at the issue. The HV section is dangerous and should be dealt with by a qualified TV repair technician.

Thank you,
I hope this helps
