your tv needs repair one of the transistors on the neck board is bad..the neck board is connected to the picture tube end inside the tv..but be care full as it stores very high voltage.if you are not a tech have a tech look at it.
The picture tubes in Zenith sets (I assume it's a Zenith since you posted this with a Zenith heading, although it's also true for any set this old) were only expected to last around 7 years. Your description makes it sound like you are missing green, or that the green is just way low. This is a common sign of a bad picture tube. There are other possible causes, but tube failure is the most likely. The low replacement cost for small TV sets makes repairing this one uneconomical.
Get rid of the set and treat yourself to a new one.
Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.
This is very typical of a Zenith set.Your picture tube will have to be replaced.One of your 3 primary colors (red,green,&blue) have turned off leaving you with the color of the dominant color.I would heave it.
Well there are many causes for this. In the back of your tv there are three different color projectors. One red, one green, one blue. One or more of them seems to be out of alignment. They can be adjusted but it is recommended to be done by a professional as there are transformers in the back near that area that create the high voltage current needed to run the color guns.
Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck
