    Its definitely worth fixing you can get the parts for around 0 dollars, and if you can solder you can do the repairs yourself in about an hour. Let me know if you need some instructions on how to do the repair.

    It could have put a strain on the ICs but this is a common problem usually about every 4 to 5years you can figure on redoing the ICs. Tomorrow I will post the instructions , par numbers and where to purchase them on line.

    When you open the back panel. The board on the far left side is the convergence output board. You will notice 2 large black chips (ICs) Attached to a large Heat sink. The board location numbers are. IC2701 and IC2702 They should have the number STK392-120 stamped on them. These are the parts you will be changing.Make a diagram of which wire clips you will need to remove and mark each clip with tape and a number so you can identify where they go back when finished. When you get the board out. Locate 6 Identical resistors right next to the ICs Their number locations are R2719 throughR2722. One or two of these tend to burn out when the ICs go out.. Just de-solder the ICs.. Radio shack sells a de-soldering Iron with a rubber bulb on it. This works great to remove the old solder. You will also need a pencil type soldering Iron with a small point 30 watt to solder them back. Also they sell heat sink compound you will need a small tube of this as well. After you locate the ICs post a message and I will post a link where you can order the ICs for about 10.00 each and the resistors if they are needed. Let me know if I need to clarify anything more for you.

    Zenith Model R40W46 use STK392-120 for the convergence ICs their numbers for the PC Board locatons are IC3701 andIC2702.

    Just order STK392-120 and you will have the right ICs designed for your model.

    Check the solder connections on the pins. Are any of the pins bridged with solder? se a magnifying glass to ake sure none of the pins on the new ICs arent touching.

Images have some ghosting, but convergence lines seem to be OK. For example, white images have a yellow shadow to the right of image. Any suggestion?


Some easy steps to determine where and what your problem is:


1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

Blueish hue throughout picture, like a blue ghost a couple of inches to the right of objects on the screen


Your TV's Convergence may be out of line. To adjust this do the following.

1) Press the Menu button on your TV/Remote
2) Scroll through and select the "Advanced Features" Menu.
3) Select Blue Convergence
4) Use the V keys on your remote till the cross hairs are all lined up in the middle of the screen and the center one is white.
4a) You can use the "Video" button to switch between the red & blue cross hairs.

A ghost blue color and it will no line up with the white cross.


The convergence circuit for the blue tube has failed. You have 2 options:
1 - you buy a repair kit and you fix it yourself - http://www.tvrepairkits.com/xcart/home.php
2 - you take the tv to a repair shop and they will replace the entire convergence board for at least $250

Red ghosting


You need to replace the convergence amplifiers. Mitsubishi part # 267P155010 and generic part # stk393-110. If there are 2 of them in your set, replace both.

Cant get the Multipoint red/blue set right


Most likely your convergence circuit needs repair, there are 2 large IC chips with heat sinks (labeled STKxxx -XXX) and possibly depending on model a resistor or fuse may have went with it. 95% of the time this is all it is. It could cost $300-400 to have someone repair it.

Convergence Problem


sounds like 1 of the convergence chips are gone theres 2 of them and better off replacing both as the other would just go a month down the line there might also be a resister or 2 gone, the price for that kind of job is around 150 +vat.

hope this helps
