Convergence Problem My TV has blue and yellow shadows on the right side of each image on the screen? I am not sure as to how to resolve this. Please help!

    There is a yellow shadow to the right of all images on tv. The very right side of the wide screen has an inch of yellow as well. Looks like the colour has shifted over.

Convergence problems, you would need to replace convergence amps and look for any return resistors to replace. The big STK's-*** are the amps.

I have a Panasonic PT-53WX54J that will not Converge

you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Hitachi Big Screen TV 46 inch Problem

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 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 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.

Yellow vertical bar on right edge of screen

Your set is starting to get a convergence problem and the only way to repair it is by changing the convergence IC's,(3)one for each color,the blue migh be showing more now but soon all 3 colors will be out of alignment and you will not be able to correct it with the custumer controls,is great that it has worked for so long without this problem,if you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for help from a pro-servicer.Let Us know how it goes.
