The blue gun (CRT) is expensive around 400 if one is available. I know a site that sells used CRTs for phillip/magnavox for 135.00 heres the link if you would like to check them out. I am one of their repair/ support techs.

No Red color at all. The convergence feature does not work either. Lots of green and blue RCA Model D52W59


Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !

Tv color turning green


could be a couple of things. 1 the convergence is messed up, go throught the set up and make sure the blue and red "+" are aligned to create a white image, If using component input make sure the red is to the red the blue is to the blue, try different cables for the components blue and red. Try S-video or Composite, if the problem persists, check the menu to ensure all the colors are set even, if the problem still persists,then you may have a blown projection gun.

Guns on their last leg- color fading


If you are asking about Guns in rear projection tv then answer is No.
Rear projection TV has 3 Guns (CRTs), red-green and blue and each gun has its unique color phosphorus coating to produce its mono color (red /green /blue) and these are not interchangeable.
Need further info, let me know.

Tv duplicate image


your guns are off and need to be adjusted. your 3 guns (red, green and blue) are off and that would explain the funny colors and shadows. Have a tv tech come out and have a look, they can fix it for a reasonable price.

Why does my TV have a red shadow on all the people and words. i've only had it 4 1/2 yrs


It sounds like the red gun is off. Your tv uses three guns(red,green and blue) to make the picture. sometimes one of these guns shifts a little and the colors get messed up and there are shadows because the gun is still trying to make the image, it just doesnt line up. This is a pretty inexpensive problem that can be fixed by most any tv technician for a small fee. If your pretty confident in your electronics know how, google adjusting guns and your tv and that should yield something.
