    The TV turns off without warning. Sometimes after being on a long time then again if only on for about 30 minutes. I have pressed the on button and input -but no results. I have unpluged the set for lengthy times, replug and it may come on or not. Sometimes I have to leave it off 24 hours. The green timer light on the front of the TV will flash twice but nothing happens, no codes, etc. Then it may not be a problem for a whole week then the next several days I cannot get it on. What now?

    T.V shuts off and does not come back on for awhile. Then will last a little longer.

    Same prob, TV has a mind of its own, shuts off erratically, sometimes not for several days, then several times in one day. This set is usually on at least 12 hours a day.

How long does it come on? If on then off, possible short somewhere, if turns off during movie, maybe weak power supply.

I hav a mit 65 in tv model number wd 60737 it comes on with the words welcome mit and green light blinks and then shuts off.


Does the led light flashes green continually?

Check if you can access the operational error code. The TV must be in shutdown and then press the front panel "activity" and "channel down" at the same time and hold them for 5 secs.

Led light will flash 2 digit code separated by a pause.

23 - 2 blinks pause 3 blinks

Let me know the result...

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

Power shuts off 1 second after tv is turned on


Good Day,

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.

3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.

I hope this was helpful, BIG IRISH.

No Power


does the front green led light flash?
unplug the set for 30 min then replug try to turn on. if the light does not flash then i might be a main fuse. Point... main fuse falure ussally means more than just fuse. if the light flashes then you have a shutdown condition. This set processor shuts it down for 1 or 25 different reasons as technicians we have a computer that reads errors much like a cars error codes.

Tv will not power up


the itc222 has a processor that shut it down for one or 20 different reasons. generally it is for high voltage safety reasons. the first thing as a technician i check are the horizontal tansistor and flyback. The first thing you can do is unplug for hour and then try again. This usally dosent work but it does elimate proscesor lockup. since the light comes on then you can elemante the main fuse. as a technician we have acess to computer equipment much like the one on cars that read error codes that tells me why the set shut down. does the set try three times then shut down.or just shutdown with one try.

Error Message


. Set shuts off after displaying the message "TV will shut down in a few seconds. Please check if the air flow is blocked." After shutdown, it may have a yellow status LED, self diagnostics indicates error code 38. To repair, replace the Lamp Thermal Sensor with the new version, part # 299P313010A. The sensor is located on the Lamp Cartridge Housing. See Service Tip VS-72B. Under rare circumstances, when a replacement thermal sensor is not available, refer to the original Service Tip, VS-72 (page 2 and 3 of VS-72B) If error 3-4 then this maybe problem:. Check to see if the lamp is on when the unit is off (in standby) if it is components on the Power PWB... K9A20 and/or K9A21 are shorted. Also, R9A02 may be open. Possible side effects ... deformed lamp exhaust duct and damaged lamp. Replace PWB-POWER part # 934C228003 and if necessary, Lamp part # 915P049010, Lamp Exhaust Duct part # 642B155010, and/or Lamp Exhaust Duct Cover part # 642B156010. See Service Tip VS-73 2. If the lamp never lights suspect the Lamp part # 915P049010

POST Replaced Bulb Problem, Error code = 32


This unit will not go into shut down because the lamp timer is not reset. The error you are getting means the lamp you put in is defective or it is not seated proplerly. Make sure the lamp door is on properly because there is a lamp door safety switch that must be depressed properly or the unit will shut down. When the timer needs to be reset you simply get a message on the screen that tells you so, it does not shut down. There are other things that will cause this problems such as the ballast or even problems in the light engine.
