My tv comes on, the power light comes on, but it won't stay on, it goes off by itself a few seconds later. Is there a solution to this?
Same problem. The TV clicks, the light comes on, the normal power-up buzzing sound... then another click and the light goes out. Black screen the whole time. I have tried unplugging and waiting for 5 to 10 minutes, but the reuslt is always the same. Bought the set in 2002. Until now, it has been wonderful.

Re: Tv won't stay on
solid state devices usualy fail at turn on or turn off time so it is
possible for a part to fail at this time and the set worked fine
earlier in the day
one thing you could try doing is unplug the tv for 30 mins or so then plug back up and restart it up and see if it works.
If it does not then you could take the back off and check the fuse and
see if its blown if so you may want to change it and see what happens.
some times a fuse does just fail
but usually there is a reason for the failure.
Another thing is that it must be going into the protection mode to
avoid any further damage to the internal circuits.This is possible if
you had a power outage.Replacing the fuse can solve this sometimes if i
is not a major problem.
Finally i would recommend you to get it repaired if you problem doesn't get solved since that is the only solution to fix it.

Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards

This is a common problem with the ITC222 chassis, I would check CP120, CP140, CP150 to see if they are bad I suspect CP150 is the one that is bad. Its value is 2200uf 16VDC. It is located on the same board as the IHVT and is in between the Heat sink in the middle of the board.
After further inspection, I believe that you have a blown convergence IC. Most posts point for two IC's. I only have one. STK393-110. There are 12 - 3.9ohm 2w resistors around it . I think they may be bad as well. The 2 Pico fuses feeding that circuit (+24/-24) may be open also. So, with that said...... Think we have the problem cornered?
i have seen this before and it may be the front power button being stuck and when your remote turns it on the stuck button turns it back off again. I have an older mitsubishi that will not boot up right sometimes and i have to unplug it and plug it back in fot it to come on. I used to pick up broken tv and fix the power buton and resell them
