Green and purple dots waving on screen

I have green and yellow dots that float around and wave on the screen of my TV. I have had the TV for a year and a half when the problem started. I had a technician come out and he did not know what was causing the problem. He reset the TV with a code that he typed on the remote. The problem went away for a month and a half, but now it is back. Do you know what is wrong with the TV or do you know the code so that I can try the reset again.

Hi, this sounds like your TV needs De-Gaussing, the screen has become magnetised and the electrons being fired at the screen are being diverted or scattered and mixed to the area's that are magnetised creating the odd colours, what you need is a de-gaussing coil, you can wave this in a pattern to de-magnetise the screen thus allowing the electrons to flow properly to the screen, it may also be the PTC on the tv's PCB near the mains input, if this is faulty the tv's own degaussing coil may not operate properly, you local TV technician maybe able to help with this as the part is specific to the TV, they maybe able to degauss it too for a small fee.

Here's a better expaliation ---> CLICK HERE <---- it shows a circular pattern here but there are many kinds of pattern magnetism can create but the colours are nearly always the same just in different places witn different strengths.

Hope this helps.

Insignia 26" HDTV 1080p, I just bought it the

First off what type of input are you using going from the ps3 to the tv. If your using HDMI try changing the different video settings. Black ops actually has a lot of problems right now on ps3. So I wouldn't use that as the basis of what is working or not, I would try other games to see if it's working. Adjust the video settings on the ps3 and see if that helps. If that doesn't try using component cables and see what that does for you.
Thank you,

Blue dots all over screen

You need an optical block. PN: A-1132-202-A. Part is very expensive with a $1500 core charge. Consider replacing the TV. Sorry, this is will eventually happen to all Rear Projection LCD televisions. The UV light emitted from the projection lamp destroys the Blue LCD panel first (shorter wave length), then the Green then the Red. The panels are not serviceable, the entire unit must be changed. I hope this helps... it will save you a $100+ service call fee anyway.

I have purple heads on my tv

Maybe you have some kind of magnetic material on top of the TV. TV screens respond to magnetic field. If the problem is not caused by a magnetic material being near it, then it is the degauss (meaning demagnetize) circuit inside. You can also degauss a screen using electromagnet. If placed around the screen of the TV in the right way. I have never used a magnet to demagnetize a TV screen, but maybe orienting the magnet at just the proper angle may also demagnetize it by cancelling the magnetized area. You can also make a TV screen demagnetizer using a loop maybe made out of plastic tube and winding enamelled wire onto it. The loop has to be about the size of your TV screen. Make sure you put tape over the whole thing, and connect a plug so you can plug it to the ac outlet. Once plugged in, the ac current will produce magnetic field to cancell out the magnetized area, when you wave the loop around your screen. I once made this as one of my tools when I worked at a TV repairshop.

Toshiba 50hp66 picture waves

Please describe the 'waves' and what you are watching when it happens, is it on everything? e.g. normal TV and when watching a DVD? Are the Waves a grey close pattern going diagonally across the screen for some other sort of pattern?
