TV won't power on. Power light blink twice then fad out. Left powered off over night. Power Light now comes on then goes off after a couple of seconds.
This could be 1 of 2 problems 1: a bad CRT, one of these CRT guns are causing the X ray protection circuit to trigger. you would have to replace all three of the guns for proper fix.(unfortunately they are no longer available). 2: bad focus block G2 is too high or too low if adjustment of G2 doesn't fix replace the focus block. refer to a technician to do this serious damage can happen if improperly adjusting or replacing.
Error code 2 1 is from the x ray protect or high voltage circuit. there are many individual components that can fail and cause that shutdown.
to repair you would need to be experienced at troubleshooting electronics and would probably also need a schematic diagram. or have a shop repair for you.
SOURCE: Error code 1 2
I found this list of codes
Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

Does anybody have a "how to fix this" for dummies. It appears this is a major problem in Mitsubishi projection sets. I have the WS-65613 and this has recently started. If anybody has a clue on repair,please provide anything. Randy
SOURCE: Mitsubishi wd52525 shows error code 37
error code 37 is either the dmd fan or the lamp fan. you can see the dmd fan with the cover off. you cannot set the lamp fan as it is under the light engine. I guess the easiest thing to do is get a lamp fan 299P282010 and a dmd fan 299P283010 and change them both.

The
best advice I can tell you at this point is to go to tvrepairkits.com
and order the complete convergence kit for your model of TV set, no need to
search and order multiple parts from different sources and pay multiple
shipping fees! The kit comes with original Sanyo STK IC’S , not those cheap
aftermarket or china made IC’S full pictorial
directions, the thermal paste, resistors, the correct Pico
fuses, AND free live on-Line tech assistance in case you run into a problem
with the repair. They ship out 2 to 3 day Priority mail, the next day in most
cases GOOD LUCK!!!

SOURCE: The green timer light flashes when i plug in the
MODEL NUMBER WT-46809:
2,2 is the error code for short protection.
The most common reason for this is one of the 2 pico fuses that protect the convergence circuit is blown. Changing the fuses will not help! They are green in color and soldered into the middle circuit board and are F9a04 and F9a05----look like resistors but are 5 amp fuses.
99%
chance if one or both are blown---you have to have someone change the
STK-392-570 convergence IC'S that this set uses----the IC'S can be
purchased on Ebay for under 14 dollars and the same seller sells the pico fuses 5 @ 2.95.
The
best thing to do here if you or someone you know is able is to unplug
the set and look for the fuses---middle board towards the back---there
are 5 of them and the two closest to the back of the row are for the
convergence IC----If someone checks them (like testing any other fuse)
you will know--if either or both is blown--the convergence IC got them.
I have start to finish, step by step instructions and photos of the fuses etc----If you or someone you know can solder and is handy--you may be able to do the repair yourself.
If not, shops usually charge 300-400 for this kind of repair in this set.
LET ME KNOW IF YOU NEED ANY ADVICE or help.

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
"12" ... indicates no error has occurred.
"21" ... X-Ray Protect circuit.
"22" ... Short Protect circuit.
"23" ... Horizontal Deflection failure.
"24" ... Vertical Deflection failure.
you will have to count the blinks, then there is a short pause and then following a second set of blinks this tells what is wrong with set.
