Tv won't stay on

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? TV turns on and immediately turns off. tried several times with the same result. does anyone have a solution? Mitsubishi model WS55809.

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

TV won't turn on


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
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.

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?

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,

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?

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.
