I Have a mitsubishi WS-65857 and after doing the diagnostic i get teh 2,2 that some of the gurus have mentioned it is to resolve. I was wondering if you can tell me how to resolve this? Thank you very...


Check the two green pico fuses F9A04 and F9A05 on the "Center Board" if either of those two fuses are blown then convergence ICs are the reason its shutting down with a 22 error code.The pico fuses look just like resistors but dont have color bands and they will be bright green.

I have mitsubishi vs 60719 chassis vz9 will not power up error code 21 all standby voltages are good 5 fuses are good when plugged in led 3 flashes led stays on for 15-20 sec no relay clicking or any...


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

Unit turns on for a few seconds then turns off


Usually in these sets the 2-2 error code is a shorted convergence IC----they are protected in most models (don't know your exact model number) by two pico fuses(they do not look like glass fuses and are usually in the power supply--little green parts that look like small resistor--amperage is marked on them and usually they are 5 amp) the fuses can be checked like any other type of fuse---if one or both of these are open the set will detect no voltage to the convergence chips and shut the set down. If you locate the convergence chips look for any discolored or burnt resistors around them----in most models they are light blue in color and marked 3.9 ohms---if any are white in the middle they are gone---

I do this here for free so if this helps you give me a vote here.

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.

Mitsubishi WS-65807 blinks '22'


I replaced the pico fuses and the convergence IC's. fuses poped right away code 22 . Further inspection of the board showed the coolant had leaked out of the center projector and fried the board. Not willing to pay $300. Passed it on to someone else

WS-65809 ERROR CODE 22


look on the center circuit board and you will see two green Pico fuses they look like resistors but they dont have any bands on them . They will have F9A04 and F9A05 on the board next to them. Check with a ohms meter if those fuses are open you will ned new convergence ICs. Thats the first thing to check are those two pico fuses when you get a 22 error on your model.

Won't power up.


Check the center board for two green 5amp Pico fuses F9A04 and F9A05 if those two picos are blow, replace both STK392-570 convergence ICs on that same board and the set will be repaired. Fuse F9A05 will read open in circuit but F9a04 wont so its best to lift one side of those two pico fuses out of circuit to check them. (* % of the time a 22 code in that chassis its the ICs having shorted and it will blow those two picos. You can get replacement parts at the following link.

Same as everyone green light comes on for a couple of seconds than back off!!!


ok, the problem with short detect....
unsolder all convergance ic's and try to turn it on.
does it come on?
if no, check all diods in the power suppy area.
check h-output
unsolder all convergance ic's and try to turn it on.
does it come on?
also might have a vertical ic.
mmm, check all fuses including the solder in pico fuses.
beleave they are sold green color.
when i get one that comes in they have 1 or 2 blowed pico fuses and that means convergance ics need replaced along with fuses.
good luck!!

2002 Mitsubishi VS-50111 WIll Not Stay on


FIRST Check for open fuses F9A04 PART # 283P044020 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF fuses are open then convergence output circuit would be your problem.
