My Mitsubishi WT 46807 will not power up. The green light on the front stays on for approximately 2 seconds and then goes out with no audio or visual. I tried unplugging the set for about 15 minutes but this did not help. Any thoughts or advice? Thanks.

Do the self check this model has, when green power light comes on and then goes out on the front of the set press and hold both the Menu and Input (device) buttons at the same time for at least 5 seconds, then release both buttons and watch the power light, It will blink a two digit code, a error code.

Most common is 2 blinks, 2 blinks, a pause and then it will repeat the code several times.

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

This is a self check meant to narrow down what kind of problem the set has.

Make a comment here so I can help.

hi,
Error code 2-2 indicates "Short Protect Circuit" problem in tv.
Need to check pico fuses in power supply as one or two got blown due to bad convergence chips.
Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses.
Unplug tv from wall socket before to repair/check any thing inside tv.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

When you try to turn it on and the green light goes off:

On the front of the set press and hold BOTH the Menu and Input buttons for at least 5 seconds and release both buttons.

The power light should blink a two digit error code; the most common is 2, a pause and 2 blinks; it will repeat the error code at least 5 times.

If it is 2,2 I can tell you exactly what is wrong and have instructions on how to repair it yourself.

This site is supposed to email me if a client responds to my answer but there have been problems lately with this.

If this happens:
If you want the instructions (they tell you everything you will need and exactly how to do it) let me know here by using the "add a comment" button.

There has been some trouble on this site lately where I do not see the comment; if this happens email :"[email protected]" and tell them you want them to contact me for the instructions.

The other option is you can also email "[email protected]" who is the community manager here.

If the site does not notify me of your response I cannot get the FREE instructions to you.

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.

MY FRIEND YOU HAVE A POWER SUPPLY PROBLEM AND MAYBE THE CONVERGENCE IC'S ARE BAD.THERE ARE A FEW TRANSISTOR IN THE POWER SUPPLY THAT HAVE TO BE REPLACED FIRST.

THAT'S CORRECT, YOU NEED SOMEONE WITH ELECTRONICS SKILLS TO FIX THIS PROBLEM. YOU HAVE A POWER SUPPLY PROBLEM AND I BELIEVE THAT THE CONVERGENCE IC'S HAVE TO BE REPLACED TOO.SO CALL AN EXPERT IT WON'T COST MORE THAN $350.00

You need a multimeter to diagnos the issue. I have one with the same problem that i had gotten for free. I found that two of the fuses that are soldered to the middle board are bad... i have not tried replacing them yet but i will repost.
