    I have an older Phillips 42" Flat Panel TV and the original remote. My problem is I just moved the TV and now every thing that should have the color blue is green! On the remote it will not let me access the tint, I can change contrast, sharpness but nothing to do with the color??? Any ideas?? It has had great color in the past and it is set for HD TV!!! It is drving me crazy!

You may have a convergence problem. Here are some of the most common symptoms.
 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

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. 

>>>Solution<<<< 

You need to replace the convergence chips and convergence resistors. 

Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

If you tried to clean the mirrors or someone else tried, there may be an object on one of the picture tubes. I've seen this happen. In one case I repaired a projection TVwith a piece of black tape across the red tube. It may have left the manufacturing plant this way. Please check and see if a cloth is laying on one of the projection tubes. If not, you have a contaminated picture tube, replace the fluid. Thanks for asking!

It was a convergence problem, both chips goes bad bad also look for bad resistors around the circuit? This is not an easy repair for non skilled person? You need to realign it after replacing the chips? Don't be cheap pay someone to do it right?

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
