Green and Red guns seems defective and requires replacement.

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.

Images on tv are green sony 60 in projection sxrd-


If it's bright green with light lines from side to side the green gun is shorting out. You would need to take the front off and look at the neck of the tubes. See if all three filiments are working. It will be a dim glowing in the neck of each tube. If you have filiment voltage but no red gun you may have bad solder connections on the CRT modules but being it's a Sony it could be a bad green Tube. If the green gun is shorting out call around to TV shops in your area and ask them if they have a Beltron or BNK Picture Tube Rejuvenator. Sometimes the short can be cleared using the right test equipment. Ask them how much they would charge you to shoot the tube if that's your problem. If it's no Red it may be bad solder connections on the CRT modules. I hope this helps.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

No picture


These sets have had, unfortunately, bad picture tubes. The gun welds tend to break loose over time.
