    it has 2 blinks and then 1 blink. I did it twice to make sure it wasn't 2-2.

    could a problem with the cable cause it? Our cable provider has been out and is coming again tomorrow due to fading in and out of the picture and a signal problem with the box that he supposedly fixed.

    repair man came out, it needs a new power board, it is $6-700. If it had been around $300 we might have gotten it fixed, but think will look for an LCD.

    two blinks and then one blink is error code for X-ray protection---means problem is most likely in the High voltage circuit of the set---the set will detect something is not right and shut down----a lot of possible causes for this----someone needs to go into it with a schematic and start looking for shorted parts in the High Voltage circuits.

    set has self diagnostic feature; when it goes off press and hold Menu & Input(device) buttons on front of set for at least 5 seconds and then release both together---set will (power light) then blink a two digit code----ie: two blinks, a pause and two blinks is 2-2 which is the most common error on this set---let me know what you find and I will tell you what it means.

No, if blink code the problem is in the TV set--cable will not cause this type of trouble

Tv wont turn on

hold the menu and input/device buttons for 5 seconds and it will blink you a 2 digit code
1-2 normal operation
2-3 i believe is short circuit protection = probably a convergence failure
here is a link to my tutorial
Let me know if I can be of further assistance.

Green lite turns on for 2 second and then turns

Please listen and try this:

When the power light comes on and goes off, on the front of the set press BOTH the Menu and Input (Device) buttons at the SAME time and HOLD them both for at least five seconds and then release both.

The power light will blink a two digit error code and will repeat it about 5 times. To get it to repeat you would have to unplug the set and turn it on again etc.

The most common error is 2 blinks, pause, 2 blinks.

Let me know what error code you find and I will direct you as to what it means and what may have to be done.

Mitsubishi ws 55311 format issues

Apparently I did not have the correct remote to go with this television. The remote I had was a Mitsubishi, but I was able to obtain one that had the 'format' button.

Bad convergence, now wont turn on at all.

The convergence ICs have failed and thats what is shutting the set down. You will need to replace both convergence ICs they are STK394-250 you can get replacement ICs at the following link with free shipping and free instalation instructions with pictures s you can do the repair yourself. Here is the link.

You might have a bad power supply or convergence circuit, I also suggest you to check for fluid spill on the circuit board. if the convergence is defective one of the 5A picofues on the power supply is open. Hope this help you.
