    Hitachi 50UX23KA. It is an older TV so I don't think it is worth spending alot of money on.

    Have blue shadow on my screen, tried to move the blue crosshair over but it will not go all the way to the left over the red and green

  • Exio Jan 21, 2008

    i'm having this same problem on a Toshiba TheaterView. The blue is off
    center and is jittery. I configured convergence, but when changing the
    blue, it doesn't help anything -- it doesn't really even change at all.



    I have electronic background, and I would like to fix this myself. Is there any sort of direction I can start looking?



    Thanks!!

    Pioneer Projection Colour Television SD-T43W.

    Blue convergence moved to right. At first was able to correct it. However after a week or so it went again, and though able to move it slightly back to the left it won't go all the way. This leaves a blue shadow to the right of all images on the screen. Could this be a minor repair??

    I have a blue shadow on all images and text on the screen.  Especially noticeable with light background including Sports shows.

If the blue shadow is convergence you should have an option for convergence adjustment via the remote control to converge the blue onto the green. If it doesnt move then its probaly a IC problem. What make and model set do you have?

I believe I have a convergence problem...red and green shadows on images and print. What does it take to correct...estimated cost? Is it something I could do myself?


You need to purchase the convergence repair kit.Are you handy?
It comes with instructions.
A TV repairman will charge about $300-$400.
The kit is a fraction of the cost

Mitsubishi RPTV has a blue shadow/image alignment 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.

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.

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 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. 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

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Colors out of alignment Epson EMP 500


You LCD optical engine is out of alignment. This will require an authorized service center to make the adjustment or even replace the unit if necessary. There are 3rd party companies that offer this service, perhaps in your own town or nearby. You may want to weight the cost of repair to purchasing a newer unit.

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.
