Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

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 directiHitachi 43VWX10B Rear Projection Television - colo - 2c07611.pngnvergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

I have a problem with the red not lining up the way it should. Screen shows double pictures. Magic Focus doesn't even fix the proplem. Got a code 5. Was told that the video board needs replaced but can't find a part number for it. Most places even want $100 or more just to come look at it.

Either the pins on the convergence ICs need to be resoldered or the ICs need to be replaced. These are large black ICs attached to a heat sink and should be marked STKxxx. Resolder first. If that does not resolve it, replace the ICs.

I hae a Hitachi 53in, widescreen, on the screen it looks like the colors are seperating. Would this be the lenses, if so how do I recalibrate them? Thanks, Drew

That would be the convergence. This usually can be adjusted either through a menu or by adjusting controls inside the set. To do this properly, you need a signal generator to create a grid on the screen so the three colors are aligned with each other.

Digital Aray is off. We are seeing 3 or 4 of each image. Each one a different color.

Your convergence is very "way off."

You should be able to adjust it by going through the menus until you find the one option for adjusting convergence.

Note that this allows a finite amount of adjustment. If the television was dropped or roughly handled, a mechanical alignment may be in order. Preferably by a tech that makes house calls to minimize the amount of movement and reducing chances of reoccurring.

Red color is not aligned

Try adjusting the convergence. If it won't move see below

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400

The problem you are facing is a common problem in all rear projection TVs. It's called convergence. If you go into your menu there is an adjustment for it. if it doesn't move back into alignment then you have a more serious problem in the convergence circuit which will require replacement of components.

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
