I have a red and blue shadow in my picture

There is a red and blue shadow in my picture and have tried to fix the convergance, but it shows my blue is alligned and the red just won't allign. Some of the allignment lines are actually slanted. No matter what I try I can't seem to line them up, I can't even get them close! What do I do?

    I am experiencing the red and blue shadowing too but my problem includes a concave warping of the overall picture. Tried to use red balance adjust but it did nothing. Its like watching a 3D Imax Panoramic movie without the glasses! Help!

    This is the second time this has happened in the last 2 years to this tv. Had a repair man fix it the last time and cost my parents $260.00 to have it fixed. I would like to find out if i could fix it for them instead of a repair man. The red and blue shadowy lines look bad. Must of been something simple because it didn't take repair man very long to fix it. What do i need to replace for what ever is wrong?

My hitachi tv's picture is distorted red and green like a 3-d pic


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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - 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.

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 solution

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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

I am getting a double image on my 48 inch television how can i get rid of it? it is showing colors green and red on double image


Assuming that your TV is a rear-projection TV, then it sounds like the separate red, green & blue tubes aren't set correctly.

Each tube needs to be alligned exactly to produce the image on the screen. If any of the 3 are mis-alligned then the effect you describe is caused.

Somewhere in the menu settings, will be an option to set the Convergence. This option will allow you to set the allignment of all three tubes.

Older sets do not have this option, and need to be adjusted via controls on the main PCB.

I have a red and blue shadow in my picture


IT sounds like it needs to be degaused.
Before checking this, check for speakers placed by the set. this will cause it too.

The best way to avoid this situation is
  1. Don't place unshielded speakers near the set.
  2. Don't move the set while it is turned on.

The coil that is used is about $50 and can sometimes be found at industrial electronics stores. It's called a degausing coil. most TVs have a version of this built in and mutiple power on/off/ons may fix it, but don't hold your breath...

The trick is to turn the coil on with it right up to the screen. Move the coil in a big circular motion parallel to the screen as you S-L-O-W-L-Y move away from the screen. when you are as far away as you can get [about ten feet] turn the coil off. Caution. KEEP HARD DRIVES, CREDIT CARDS, AND FLOPPY DRIVES AWAY from the energized coil!

Good luck

Ken

Has a shadow on picture. Red, Green is not alligned


You need to set your convergence. Check your owner's manual on how to do it. I'm not sure the exact procedure on that model, but usually you can find it in the setup menu of the tv. What you're trying to do is line the red and the blue up perfectly with the green so that they all blend together to give you one picture.
