    I had the same problem with a WT42311 unit recently acquired second hand and not working. According to the service manual, the error code 1blink, 2 blinks = no error detected! Strange as that sounds (since the set won't power up) I think it means that the diagnostics can't truly get to the real problem due to the set not powering up all the way. I've tried cleaning one of the circuit boards, and now my error code is 2 blinks, 2 blinks, which is supposed to mean "short protect circuit". I take that to mean I have a short circuit, the tv has detected it, and the set is turning itself off to protect itself from damage. This is more that I had before so I guess the cleaning did something. I'll clean things up some more and see where this goes. I hope I don't have to de-solder and replace any parts, but we'll see.

All that is wrong is the Convergence IS's. They are located on the deflection board (IC8C01 and IC8C02) and are mounted to a very large heat sink. They are black and are STK IC's, STK392-110. Replace both IC's with STK392-120 and you're in business. The -120's are and upgrade and have a higher amp rating. The IC's can be found anywhere on the internet for $9.99 and up. Check Electronix.com, MCM Electonics, Mat Electeonics for starters. Gook luck. Gary D.

My mitsubishi 42' hd 1080 tv turns off immediately after i turn it on.The set is about 7 years old.HELP!!!!!! niteowl42


Have you acessed the power indicator error code by pressing in the menu and input buttons on the front of the set both in together and hold in for 5 seconds? The led will blink a series of blinks to indicate a 2 digit code which will repeat several times. Let me know what the blink seqience is.

My t.v. dont stay on


Hi,

First do a hard reset. Merely unplug the power cord for 4 hours, then restart it. This will correct it if the cause is corrupted soft codes.

If not, the protection circuit has captured the power management and you must have it looked at by a service tech.

Let me know if there is more.

When i press power the timer light flashes and the T.V. turns on and right back off.


If model number is WT-42311 do the self check the set has.

When power light comes on and then goes off, on front of set press both the Menu and Input (device) buttons at the same time and hold for at least 5 seconds and then release both buttons.

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

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

Mitsubishi tv model wt-42311, error code 2-2. what can i do?


2,2 IS short protection and 95% chance it means one of the two pico fuses that protect the convergence IC chips are bad.

This model uses two of the chips: STK-392-110 and you would have to pull the light box out to replace them safely (total parts cost will be under 30 dollars).

It involves getting at the chips and the fuses and replacing them: how much skill do you have?

When I go to turn it on it clicks and then clicks off


do the self check this model has and let me know what you find:

when it shuts off press ON THE FRONT OF THE TV both the menu and input (or device) buttons at the same time for at least five seconds and release both buttons.

The power light will blink a two digit error code.

for example---2 blinks, a pause and 2 blinks (this is the most common error code)

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

I have a Mitsubishi Model WT42311 Tv . It will not stay on . When you press the power button it tries to come on but turns itself off. Do you have any suggestions?


Yes, do the self check that this set has.

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

On the front of the set press and hold both MENU and DEVICE (OR INPUT) for 5 seconds and release both buttons.

The power light will blink a two digit error code--for example--2 blinks, a pause and 2 blinks---it will repeat the code at least 5 times.

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

2,2 is the most common and the least expensive to fix.

Most units give a error code "22" short protect circuit. If so check:

Q5A00
C557
and or the
convergence IC's (STK392-110) had failed and caused a diode (D522) to short
out.
If Q5A00 check bad there are other parts that have to be checked or
replaced.
