I changed my two IC chips and three resistances on my Hitachi TV to fix color alignments. Now the problems is that yellow and blue double image are seen at the bottom of my screen with no much effect on...


Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

Ur tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts,must be replaced on the tv convergence board to fix the tv convergence board to solved the tv picture convergence problems.Try website like Tvrepairworld.com to buy a whole convergence board for the replacement,might still have it.The DLP tvs AKAI and Samsung tvs used the same convergence board.Or the shop,will cost u like 300-350 for parts and labors.

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

My Toshiba 42H83 (2004) has double (or triple) images. Is this something that can be fixed? Is the repair some sort of lamp? If so, is that an easy fix?

Double Image Red and Green


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 directions your convergence 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 www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.
