2-2 is a error code that means short protection.

Usually in this set it means one of the fuses that protects the convergence circuit is shorted because of a bad convergence Ic.

I HAVE PHOTOS OF THE FUSES-- and THE PROTECTION RESISTORS- and I also have step by step from start to finish instructions for this repair in this set.


If you want the instructions and photos give me a vote here and I will be happy to email them to you and answer any questions you have. I have done hundreds of Mitsubishi sets with this problem---I just got home from doing one a few miles away from where I live.

WS-65809?, if convergence is skewed and comes and goes, uses two of the STK-392-570 CONVERGENCE IC chips.

I have seen a lot of the Mitsubishi sets that use these two chips where the convergence jumps in and out. You need to replace both chips and adjust the set.

You can buy a pair of the chips on EBAY for less than 13 dollars plus shipping.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THE SETS THAT USE THESE TWO CHIPS.

If you or someone you know can do the repair you can save the set and a lot of money--most shops are going to get at least 300 for this kind of repair--I know as I have done hundreds of them here.

The instructions tell you everything you will need and how to do the repair. I have helped many people here do this based on my instructions.

If you want the instructions let me know and I will either post them here or send them to you.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY

I currently am experiencing my 2002 Mitsubishi diamond series tv shuttin g of after being on for 3-5 minutes


Sounds like you have a cooling issue. Do you notice if the fans inside the back of the tv are running? If not then it's overheating and turning itself off to prevent further damage.
Also The next time it happens, before you just turn it back on, press the INPUT and MENU buttons on the front panel together and hold them down for at least 6 seconds. This should cause the front LED to flash a 2 digit code. If it flashes once, then twice, then pauses and repeats, it means that the TV's computer didn't detect a problem.

hi there,

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

I have a green flashing light and my tv won't turn on.


This is cause of a power interuption. Try unpluging the TV from the wall, and waiting several min. Then plug it back up, wait serveral min again and the green light should stop blinking.Then turn it on.

Green light won't stop flashing. Unable to turn off/on or reset.


Unplug the unit for 5 minutes then plug it again. Turn it on. If it does not power up, press the SYSTEM RESET button on the front panel with a pointed object such as the point of a pencil or end tip of a paper clip. The green LED light will flash quickly for about a minute then stops. You may turn on the TV then. The changes you made most recently, before using
SYSTEM RESET, may be lost. Changes you made previously, however, are not lost.

65 in Mitsubishi rear projection tv won't power on.


Go to the set and when turning it on doesn't work push and hold down the MENU and INPUT buttons at the same time until the LED starts blinking. It should be a two blink sequence like 1 blink pause 2 blinks long pause and then repeats. Repost the blink sequence and that will narrow down what the microprocessor thinks is the problem area.

Replace all 7 capacitors in the DM Module on the DM Power Supply Board. If it is similar to the WS-65869 and WS-65513 it will have a metal enclosed DM Module at far left of chassis, looking from rear. About 4 or 5 connectors, screws, and Module slides out. Take top shield off. Take good notes or use digital camera or video recorder to make re-assembly easy. These capacitors are 1000uf@16 volts. They always check good, just replace them! After re-assembly plug AC in and wait 90 seconds or more (green Timer LED will stop blinking), then press Power button. If Timer LED doesn't stop, look for small pinhole (System Reset) and press switch with pen or small screwdriver, then wait for green LED to stop blinking. Then Power On TV.
