COLLOUR DISTORTED MY TELEVISION WORKED WELL FOR ABOUT 14 MONTHS ,NOW WHEN I TURN THE TELEVISION ON THERE ARE THEREE CIRCLES OF COLOUR EXTENDING OVER THE ENTIRE SCREEN AND THE TRUE COLOUR IS DISTORTED EVERYTHING APPEARS PURPLE IN COLOUR

If you bought it with a credit card that usually gives you a year of extended warranty so repairs would be no cost

Convergence adjustment procedure to projection televisions are given in detail.

You will need a real technical person to diagnose this by taking it apart to check the circuits. There should be some adjusting screws on the circuit boards for distortion and color control.

It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.
Thanks.

Check all of your cables on the back of the tv and your sources such as Cable,Sat box and DVD palyer to make sure they are fully inserted into the input and output connectors. Some times Component cables will work loose and you end up with a missing color. Temprature changes can affect intermittant connections. If that does work then you have a bad Main bd.

The degusser is out .
When you turn the set affter its
been off awhile it makes a thud sound
and demagnatizes the tube thats
the degusser working . cost to

If you purchased the warrenty extra above the cost of the tv Sears will allow you to purchase another extended warrenty. Contact them and let them know your extended warrenty ran out and you would like to buy another. I would leave out the part about the tv being broken.

Your screen mask may have become magnetized. This will require that you have the CRT degaussed. This is done with the use of a degaussing coil. you have to stand about 10 feet from the TV with the coil held vertically and moving it in a circular pattern as you walk towards the tv. Once you are about 1-2 inches from the TV stop and continue the circular pattern for about a three count then backup from the tv still using the circular motion once you are about 10 feet from the tv turn the coil to a horizontal plane and move it away quickly and turn it off. This should degauss the TV and remove the color distortion.

You will need a degaussing coil to perform this task.

Sounds to me like your digital board is bad.
