Check f2,f3 fuses also: this could be error 23
overheat check the ic's and, chips: chroma etc. for the proper amount of heatsink grease
you didn't accidently ground a component i.e. a pico or, reverse a dip? Do you have a good scope wave form on the B+ of your power supply? that's all I can think of right now hope it helps.

Mitsubishi convergence issue


First is consider what the issue is: nothing moves convergence wise or only one color etc.

Also follow if needed the voltages from the pico fuses involved---one will be a negative voltage and the other a positive one--follow them from the diodes for each voltage to the chips---"Got Voltages?"

Will bad convergance ic's keep my Mitsubishi


If one of the two stk-392-570 chips has shorted it will blow a pico fuse on middle board and set will not come on.

Plug set in, turn on, when green power light goes out on the front of the set press and hold both the menu and input (device) buttons for at least five seconds and release both.

Power light will blink a two digit error code: if 2,2 it is a blown pico fuse and the chips also must be replaced. I have start to finish step by step instructions that are available if the customer selects me to answer in the new Marketplace here on Fixya.

see attached photo of chip and also part of middle board with the green pico fuses.

Mitsubisi wt-46809 will not turn on. i plug it in and it blinks 3 times then nothing. no error code when i hold menu and input


keep in mind if you unplug set it clears the error buffer.

Try to turn set on and if power light comes on and goes off then do the self check; menu and input for at least 5 seconds and release both buttons.

UNPLUG TV ANDTHEN PLUG BACK IN---TURNON---GREEN POWER LIGHT COMES ON FOR A MOMENT ANDGOES 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 protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


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


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Before you rate this information let me know what you find.

Mitsubishi model Wt-46807 Power shuts down after turning on. Tried the solution of pressing the menu & input buttons at same time for at least 5 seconds. Power light error code was 2 blinks/pause 2...


hi,
Error code 2-2 indicates "Short Protect Circuit" problem in tv.
Need to check pico fuses in power supply as one or two got blown due to bad convergence chips.
Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses.
Unplug tv from wall socket before to repair/check any thing inside tv.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

WT-42313 - Won't turn on. TV gives and error code of 24. I found that this is an issue with vertical deflection. I need to know how to repair this issue.


Ck pico fuse F9A05 5amps it will be green or yellow looks like resistor if bad, replace Both STK ICs STK394-250 and 2 resistors R8c13 &14 3.9ohms also resolder all 3 yoke plugins on board.

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.

My TV not powering on. It clicks and power lightgoes green, then

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!!!

Mitsubish WS-819 Protective Shutdown. 2 blinks, pause, 2 blinks


Over 95% of the time a 2 - 2 blink code on that model is a convergence output problem. You need to replace both of the convergence output IC's and perhaps the pico fuses feeding them voltage. The pico fuses are F9A04 and F9A05. They are on the same board with the convergence outputs.

Green indicator light flicks about 3-5 times


The power supply has likely detected a short circuit. Hold the front panel INPUT and MENU buttons down for 5 seconds then read the code from the green light. If the light flashes a 2-2 code (2 flashes, followed by a 1/2 second pause, followed by 2 flashes) then pico fuses are blown. A 1-2 code indicates that nothing is wrong. The likely cause for blown pico fuses (FA904 & FA905) is a bad convergence driver IC. The PC board must be resoldered to replace the ICs and fuses.
