Colors on tv are seperating. looks like double images.


Hi, Try the auto convergence or auto focus to eliminate the problem, if this does not work, you may have to get the TV repaired, the common problem are the power amplifiers that correct the color convergence, that is why you get color shades or ghosts in the images.

Color is distorted. Green, red, and blue ghosts


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

Color ghosts out of allignment


This is a convergence problem that can be as simple as poor connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself.

Let me know if you wish to attempt the repair and I will post additional details and instructions.

I have a Nikon D200 camera. It's now 2 years old and I'm having difficulty with the auto focus. The camera focuses but it comes in and out and I have to depress the shutter several times to get it clear....


the auto focus works on the basis of contrast. If you aim your chosen auto focus square at an item that fills that square with only one color or shade of color light a blank wall or a solid blue sky the camera can't focus because it is trying to compare the contrast in order to focus the camera. try to make sure that you choose an item with contrast to aim your auto focus square on like someones eye and part of their cheek so the camera can see somre contrast to evaluate then focus. Obviously you depress your shutter half way to activate the auto focus let the camera do its thing keeping the shutter half way depressed move your field of vision to where you want it then fully depress the shutter to take the picture. the camera relys on seeing some contrast within your autofocus square in order to auto focus
