The flashes you've mentioned is a "12" error code which is no error has been detected by the processor.

Double check the error code by following the steps below.

Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the *** (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four

Let me know the result.

Getting codes of 2 flashes then pause and then two more flashes. What does this mean

Error Code Operational Check

Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occurred since the last Initialization

An error code of 22 indicates a shorted component or shorted power supply line.

Power will not come on even after system reset. Pushed reset and LED flashes then after it stops flashing TV will still not turn on.

do self check: when it shuts off and power light goes off:

On front of set press and hold both menu and input (device) buttons for at least five seconds and release both buttons.

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

Let me know what error code and I will assist you

Mitsubishi WS-55857 turn on/auto turn off problem

After it shuts off, you need to get a code from the tv by pressing the menu and device buttons together for 5 sec. A code will flash at you made up of 2 digits. Example. 2 flashes a pause and 2 flashes points to a convergence failure. If this is not your code post yours and I will help you.

Could be convergence. Check the error code by pressing menu and device together for 5 sec and the timer light will flash a code. If it flashes 2 times pause and 2 times again it is the convergence IC stk393-110 and 2 fuses. Goodluck.

Here's the basic troubleshooting:

  1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
  2. Disconnect ALL devices from the TV.
  3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
  4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
  5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
  6. If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
  7. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.
Please let me know the code you got and I'll tell where the problem lies and how to fix it.

Stays on for 2 seconds and switches off

A 2-2 code on that unit means over current shutdown. 95% of the time that code indicates defective convergence output IC's.
