The manual is almost impossible to find. But that chassis usually only has 1 IC that powers the convergence. Usually a STK730-020 or simallar. post the number off the IC you see up front and I will cross reference it for you and post a link where you can get a replacement

Convergences not linning up and bowed after replacing a blown fuse


This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.
Here are some images of convergence problems.

There are 3 distinct color lines and the picture looks 3d. The lines are bowed and trying to adjust using the convergence grid doesn't work- the grid is bowed


Mitsubishis are notorious for bad solder connections on the convergence IC's. These are located on the big heat sinks on the main board. It's an easy fix if you know how to solder. Check for any play on the IC's when "wiggled".

I had to replace a fuse for the power supply and know the picture is blurry and bowed


Your convergence power supply is propably not working. The convergence supply board is mounted above the mainboard and has AC 110V supplied to it from the main PCB. That's probably why the fuse blew.Rca Has abulletin regarding replacing two diodes CR19710 and CR19713 on convergence power board.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Distorted picture


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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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 fix

Convergance


the regulator will sometimes blow the fuse when it shorts. Hopefully the regulator will solve the problem if not you will need to trouble shoot the convergence board itself
