2, THEN 3 IS ERROR CODE FOR Deflection circuit problem---means something in either the Horizontal or Vertical deflection circuits is causing the problem.

I doubt unless you have a circuit diagram and a volt/ohm meter that you are going to resolve it.

I do not often suggest this but I think you should consider having a pro look at it--tell them what the error code is--that will get their attention and also tell you if they know enough to help.

Sorry for the not so good news.

If you have questions let me know.

    2 THEN 3 is NOT a bad convergence chip-----someone out here needs to learn the error codes for this model:








    Normal
    0


    false
    false
    false

    table.MsoNormalTable

    mso-fareast-language:#0400;
    mso-bidi-language:#0400;}








    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


    These are the error codes for this model---only one that indicates bad convergence chip or chips is 2-2------short protection.

    IT IS important to know the right answer before you post a solution--I happen to know.

Hi my name is Roety,
I can help you with your issue ,
Most likey you need the convergence ICs replaced.
A repairman would charge about $350 to replace them
Voltage checks and a visual would be needed to determine exactly what is bad in your TV

The model listed has a self check: when you turn it on and green power light comes on and goes out in a few seconds, on the front of the set press and hold both the Menu and Input(input may be labeled Source) at the same time and hold for at least 5 seconds.

Release both buttons and the power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat for a total of 5 times.

If you have unplugged the set you will have to plug it back and turn set on, let it fail and then do the check--removing power clears all errors.

Let me know what code you find.

Will Not Turn On


First you need to do a self test diagnosis and then if it comes up with:
SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
Do self test by pressing Input/Device and Menu at the same time for 5 sec. the set will show a 2 digit seq. first blinks followed by a short pause then the second.

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.

Have a Mitsubishi WD-62327 DLP projection TV. It is a few years old. Would not turn on. Blinks red - 3 short red blinks then 1 longer blinks - and repeats. We have disconnected everything, unplugged,...


if you hold the input and menu button for 5 seconds it will flash you a code 36 is the lamp fan / dmd fan has gone bad. pretty common. not hard to change but will cost 100 in parts and whatever labor may be

Tv turns on then off after a few seconds. No picture or sound in these few seconds.


Try this and let me know what you find:

Green indicator light flicks about 3-5 times


The power supply has likely detected a short circuit. Hold the front panel INPUT and MENU buttons down for 5 seconds then read the code from the green light. If the light flashes a 2-2 code (2 flashes, followed by a 1/2 second pause, followed by 2 flashes) then pico fuses are blown. A 1-2 code indicates that nothing is wrong. The likely cause for blown pico fuses (FA904 & FA905) is a bad convergence driver IC. The PC board must be resoldered to replace the ICs and fuses.

No picture


Self test: Turn on and Press the input and menu buttons on front panel together and hold for 5 sec. after 5 sec the power LED will blink a 2 digit seq. This will let you know what error code. Count the first blinks then a short pause then the second blinks. Example 2-3, 3-4, 4-1. Let us know what it is.
