Question about Mitsubishi WS-55809 55" Rear Projection Television

1 Answer

I had the 2 2 error code and replaced the two IC's and the 5 amp pico fuses in 4 and 5. Set worked fine for several days and then came up with 2 4 error. My son watched tv last night with no problem and now it won't turn on again and has 2 2 error. Both pico fuses are blown again. Any ideas?

Replaced Convergence chips, same problem


This set has pico fuses on convergence board and also on G power board, there should be 2 5 amp pico fuses on power board.

If convergence is bad exactly as before double check the power board fuses and check to see if voltage (it is marked!) is there with power board disconnected from chassis..

A blink of 4 times is an error code that there is no vertical deflection. There may still be a problem with the + or - 15 volt supplies. This error is generate when the vertical deflection pulse is missing. there might be a problem with ic 8003 wich is the vertical drive ic. this chip generates a signal witch is detected by transistor q 8001 check pin 3 to see if you have 4 volt stop signal

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.

Mitsu WS-65909 COMES ON AND TURN OFF IMMEDIATLY, ERROR CODE 2-2


Two blink code on this set means Usually one of the two pico fuses that protect the STK-393-110 CONVERGENCE IC is blown--the fuses will need to be tested and the chip and them replaced--


If you have enough skill I have step by step start to finish instructions for this repair in this set---set detects one of the voltages to the Chip is not there and shuts down instantly. I have photos of the chip, fuses and protect resistors this set uses also.


If you want the instructions for free give me a email and I will send them to you for free--if you are able to do this repair yourself you will save a lot of money--you can buy the chip on Ebay for about 14 dollars plus shipping and the same seller sells the pico fuses..............


If you want to attempt this give me a vote here--If you are not able to do it yourself I have suggestions for you about getting the set fixed--I have done hundreds of these sets!

Just reply to this post here.

Let me know what you want to do, I am here to help people

Mitsubishi WS-65611 IC's replaced


this set has a self diagnostic feature; when you turn it on and the green light goes out--push menu and device(or input) together for 5 seconds. the led for power should blink an error code. The most common is 2, pause and 2---this means something is shorted. If the set functioned before you changed the stk--you may have a new IC that is shorted--this IC is protected by two pico fuses usually marked as fao4 and fao5----they are about 3 inches behind the IC and are marked 5 a(they are green in color and do not look like fuses) also check all the 3.9 ohm blue resistors in front of the Ic--if any are white in the middle they are gone and the new IC got them. you did not remove the board? you tilted the entire chassis up to get at the IC? take a good look to make sure you did not pull any plugs loose---check for the error code first and let me know what it is. Best way to do this repair is to remove the entire board from the plastic frame---takes a little longer but is safer way to get it done. If one of the pico fuses is blown you will check it just like a regular fuse--an open fuse will suggest short and the set will shut down with 2, pause. 2 errror code.

Mitsuibishi WS65809


The only items on your set that should need replacement would be both convergence IC IC801 and IC802 which are both STK392-570 and you will also need to change the two 5 Amp pico fuses which are F9A04 and F9A05 they are both % amp pico fuses. All parts are located on the center Board
