Mitsubishi tv error code 21 - Mitsubishi WD-62525 62" Rear Projection HDTV

This is a V20 chassis, circa 2002
Available error codes for this unit are as follows:

12.....No error has occurred

21.....X-Ray protect circuit

22.....Short protect circuit

23.....Horizontal deflection failure

24.....Vertical deflection failure

most of the time the convergance ic go bad:
but try this:
The 3 flashes of the led when you plug the unit in is the
microprocessor initializing.

This unit has an error code diagnostics.

On the front panel of the unit press and hold the INPUT and MENU
buttons at the same time and hold them down for about 5 or 6 seconds.
The unit should activate it's error code mode.

The led will flash count the number of flashes. It will then pause for
1/2 or 1 second. The led will flash again count the number of flashes.
The unit will repeate this for about 5 or 6 times.

You now have the two digit error code. The first time the led flashed
is the first number of the error code, the next time the led flashed is
the last number of the error code.

12 ----------- indicates no error
21 ------------- X-Ray Protect circuit
22 ------------ Short Protect circuit
23 ------------- Horizontal Deflection failure
24 ------------- Vertical Deflection failure


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

Q5A00
C557

If Q5A00 check bad there are other parts that have to be checked or
replaced.

If you are able to do above call a tech to service the unit

replace line output transformer

32 isnt a valid code for your model. Mitsubishi model WS55859 has only 5 possible codes they are 12, 21, 22, 23, and 24 Double check the code again and resond to this same post and i will assist you.

Run the diagnostics.

With the TV power cord plugged in, press the 'INPUT and 'MENU' buttons at the same time -- use the buttons on the front of the TV, NOT the buttons on the remote; a diagnostic Error Code Operational Check will begin, utilizing the 'POWER ON' LED (the green 'POWER ON' indicator light).

There will be a pattern of two sets of flashes, with a pause in bewteen flashes; this sequence of flashes will be repeated a total of five times.

The Error Code designations are listed below:

Error Code Description
12 No eror has occurred.
21 X-Ray Protect circuit.
22 Short Protect circuit.
23 Horizontal Deflection failure.
24 Vertical Deflection failure.

I hope this information helps.

X-Ray Protect circuit error code 21, make sure your counting it right because code 12 is no error

hold the menu and input buttons simultaneously for 5 seconds. the tv will blink an error code
Error Code Probable Cause
12 Normal Operation - No Error Detected
21 X-Ray Protect
22 Short Protect - likely convergence IC failure
23 Loss of Horizontal Deflection
24 Loss of Vertical Deflection

Fast Blink for 70 sec. After AC is applied = Normal - DM μPC is booting up
Fast Blink (doesn't stop) After AC is applied = TV μPC is running, but DM failed to boot up
Slow Blink Set is Off = Normal - Timer is set for Automatic Turn ON

Its very frustrating when we think we have something fixed and then forget to do something or hook something up wrong to only make what seemed like a simple repair much more complex...Here are a couple manuals if you don't have them that will help..Not sure if the last are the same as your TV but thought I would post them all in case they are...Good luck!
