Error code 22 is a short protect circuit. this means the tv has found a problem in the tv and will not let it turn on till fixed. this could be several different circuits in the tv that is causing this. we need to test some parts to see what this is. the most common is a shorted convergence circuit. a repair on this would range around 400.00. You should check using a multimeter and also you should be good at soldering

PS:I strongly advice if you don't have experience in electronics then better leave this job to a tech

    The tv has an electrical problem inside . Try disconnecting it from power (unplug cable completely) for 10 minutes if you still get code 22 after turning it back up, then there may be a major problem.

Hi,

error code 22 is a short protect circuit. this means the tv has found a problem in the tv and will not let it turn on till fixed. this could be several different circuits in the tv that is causing this.. the most common is a shorted convergence circuit. a repair on this would range around $400.00.
the fact it did this when the box shut down is odd... but i see no way it could have caused this.

Here are few trouble shooting steps you can try:

ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.

TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

Goodluck..

The error code 22 is a short protect circuit. This means the tv has found a problem in the tv and will not let it turn on till fixed. this could be different circuits in the tv that is causing this. we need to some parts need to be tested. the most common is a shorted convergence circuit. It requires hands on electronic repair skill. If you have done electronic repair I may give you some guidelines, I you don't have experience on electronic circuit repair, I will strongly recommend you to take it to a service center or ask a hands on technician's assistance as it requires circuit diagnostic-troubleshooting after opening the back cover. Please post if you have further questions.

Good Luck

Mitsubisi wt-46809 will not turn on. i plug it in and it blinks 3 times then nothing. no error code when i hold menu and input


keep in mind if you unplug set it clears the error buffer.

Try to turn set on and if power light comes on and goes off then do the self check; menu and input for at least 5 seconds and release both buttons.

UNPLUG TV ANDTHEN PLUG BACK IN---TURNON---GREEN POWER LIGHT COMES ON FOR A MOMENT ANDGOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Before you rate this information let me know what you find.

Mitsubishi model Wt-46807 Power shuts down after turning on. Tried the solution of pressing the menu & input buttons at same time for at least 5 seconds. Power light error code was 2 blinks/pause 2...


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.

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?

Error code 22 on a Mitsubishi WS-55907 55'' HDTV


your set is the V17 series so a code 22 means short protect. Which means the TV has a short circuit condition and is shutting down to prevent further damage. You can get a manual for the V17 sereis at the following link for 15.99 and they will provide free unlimited support to help you with the diagnosis and locating parts. Your set is coverd in the V17 sereis service manual under the mitsubishi section. Here is the link in case youd like the service manual and free support.

Error code 2-2


error code 22 means short to ground. for a start check your power supply to see if anything is shorted to the ground.

Tv powers on and goes off after about 3 seconds


This set has a problem in the horizontal sweep circuit or in the main power supply. Most likely a failed component, and the set shut down to protect the rest of the circuit. If you know how to read a schematic diagram and how the circuits operate, then you will need a good multimeter and an ESR type capacitor checker to find out the short in this set. Sometimes the CRTs(Picture Tubes) will leak the coolent fluid out and onto the printed circuit boards. Also sometimes the convergence IC's can cause this problem, but if that is the case the small little pico fuses will pop also. If you have had no solid state or printed circuit repair experience, play it safe and call in a trained tech. Good Luck
