    I've got the same problem with my Mitsubishi 55" HD set (WS-55511) as cujo1796 has where the set will not stay on.

    I had the exact same thing happen this morning as cujo1796 had. Power button goes on solid for about 3 seconds and shuts off. Any help would be great.

    I have the same problem. It was working and then we did an upload on our satellite TV. After that, the green light will come on for a few seconds and then turn off.

Hello,

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?

Wont stay on when cold


This sounds like a power regulator issue. Check the site www.TvRepairKits.com for a "shrinking and expanding" video kit for your model. It also fixes the random off/on when the tv is cold

NOT A GOOD IDEA AT ALL!

You likely now have one of two things happening:

1. Green power light constantly blinks and will not stop(should blink for 70 seconds and go out).

2. Green power light comes on and a few seconds later goes off.

Which do you have?

Tv automatically powers off by itself within seconds.


This model has a self check: with the set plugged in turn it on--green power light comes on and a few seconds later goes off.

On front of set press and hold BOTH the menu and input buttons at the same time for at least 5 seconds and release both buttons.

Power light will blink a 2 digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code you find and I will tell you what it means.

Last night the set just turned off by itself. When I try to power on, the power light comes on for a second and then it shuts itself off again.


I am having this exact problem. The TV turned off by itself and now when I try to turn it on, the power light stays on for a sec and goes of with a click sound.

Any TV experts who can HELP?

Tv won't stay on


Hello mrscarpenter,

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.

I hope this helps,

Tv won't stay on


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
