I doubt that the wii caused it, as this is a common occurance in all rear projection TVs.

I have multiple colors on the screen of my 530hd pioneer elite TV when it warms up. When I try to adjust the convergence I am unable to move the red line far enough to converge on the blue or green line.


The convergence of your tv is defective try to replace it. You will find the convergence chip inside your tv, try to open the back cover of your tv but be sure to unplug the tv first. Try to look the large aluminum plate it is the heat sink, your convergence chip is attached to that heat sink it has a marking of stk-*** followed by a number you should remove it from the pcb using a soldering iron, and soldering pump but be very careful you might damage the pcb and may caused another fault to your unit. Or you can contact a service technician to save you from stress. Good day and best regards.

Toshiba 41h81 green convergence problem


Below are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Good Day, YOU ALL;
Try this: 1. E2RESET DOES NOT RESET THE CONVERGENCE. THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12598970", IF THIS DOES NOT RESET THE CONVERGENCE TRY "MENU 125968970"

2. CHECK C2P08 100 UFD 16 V OFF PIN 3 OF IC2P03 (3.2 VOLT REGULATOR) ON THE SIGNAL PCB.

Also you may poor solder connections on the vertical output IC or on the CONVERGENCE IC's.

Hope this helped, good luck, big IRISH.
