    hey can i get your email address i want to send you a picture of what the problem is........and if you could please give me the resistor locations i would appreciate it......i found 18 but they were all like 5.6 ohm......i did see a module next to the stks....it said like green something near it...green gene?

    better yet here is my email address dcxguy48080@yahoo.com

    email me so i can send a pic....


  • dcxguy48080 Jan 13, 2009

    i also can not move blue or red at all during convergence and when i go into service mode and try to cahnge gemoetry nothing happens at all for red or blue or green.........the picture looks just like this see link

    and scroll to bottom of the screen on that link you will see a pic of red blue and green way off and bowed in thats exaclty how mine looks

    is the board you are referring to called the conv gene board???

    i have seen other references to that regarding not being able to move convergence at all for all colors...........

    you mentions some caps.10uf 16v?...similar to hypermodule on toshiba???


  • dcxguy48080 Jan 13, 2009

    on this model i saw 18 resistors that said like RD they were right near the stk in groups of 9

    they all checked like 5-5.5 ohm......you said 120ohm

    can you verify the actual locations or no schematic??




  • dcxguy48080 Jan 13, 2009

    hi i pulled out the conv gene board if thats what you are referring to and the capacitors all look fine..none are bulged at all.......and there are about 25 of them on the baord...some say 10uf50 and some say 16v47uf

    i thought that when caps go bad you should see a bulge on top or is this not always true..and do you think its this board casuing the convergence to not work at all........ic ant adjust blue red or green at all even after replacing the stk and finding no bad resisors and no bad picos

5a resistors are all 120 ohm 1/2 watt use flame proof resistors.
check fuse f9a23 or f9a22
also replace knowen bad caps in this unit efecting convergence replace all 10uf @ 16v on the scan doubler module, ther are 8 off them.
make shure and check trace between Rg-8 and r705 for a open, sumtimes fulid from crt will open this up.

    yes about the same, in ref to caps, your right.

    please rate me if this was of help

    i work very hard giving out free advice you know.

    lol

    I think all resistor locations star with 5a or sa

    also get a magnifine glass look for small cracks in the resistors, I have fixed manny like this in the past.

I replaced my convergence chips and I still have a convergence problem. Its not as bad but I still cant line up the blue convergence cross exactly


Sounds like your over half way there lol..
You now need to check the resistors positioned near the convergence ic's. They are your likely problem and go bad often when the ic's fail.

They are normally about 2watt and the values will vary but normally are like .10 ohms to 1 ohm.
I cant find a schematic to give you the exact values and locations but if these resistors measure off value at all you need to replace them with the exact value of the originals.

Heres a link to resistor color code guides just in case the value numbers are not printed on the resistors

Good Luck!!!

Mitsubishi WT-42413 Red Convergence will not move left right


U check all the resistors with the Ohm Meter?All the resistors u check it in tolerance?Resolders all the resistors,so it make good resistance for the ICS?U do all these steps,u still have problems,Ur ICS some how it shorted it dead,again.

Convergence on mitsubishi WT-46805


Mitsubishi is famous for this. You are going to have to resolder the convergence ICs. Very simple repair if you are just a little tech savy. Do you know how to solder? This is a 99% fix. Take the back cover off (unplug first). You will see a big heatsink on the board (6-8 inchs long) attached to this are 2 convergence ICs. Unscrew the board, flip it over and resolder all the pins to those 2 chips. Done

Mits 46805 - Replaced IC's now picture is dim!


Good Day, Nickb2b;

The IC's you installed will not cause a dark/dim picture......but I would like you to check two things:

1. Make sure you put all cables that you may have unplugged into their proper positions, the cables are marked with numbers, ensure all cables are properly seated,

2. Look for fluid on the PCB's.

Good Luck, big IRISH.

Hourglass Picture


it easy to locate the fusible resistor in the power module PCB,it look like a resistor but white in color,normally printed soc xxxx (2100) on top of the component. After you replaced the STK392-110 , you need to re-alight the convergence setting again.hope it will help.

Mitsubishi WT 46805 ~ Picture gone..... :0(


Good Day, Corri;

It sounds like the TV has a Circuit problem in the convergence circuit. If it comes and goes then the concern can be corrected by re-soldering the 'conv' output IC"s. A semi-minor repair and cost.

Good Luck, big IRISH.
