Chances are, if it's an older set, componants have changed value through use over time, which also includes the picture tubes and associated driver circuits. The way to compensate for this color drift is through adjustments. Either turn the red down a little, or turn the blue and/or green UP. Be carefull though as there are potentially dangerous voltages in and around the circuit boards and picture tubes.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary
IF you have the serial number you should find the model number.
The model number is essential for getting more information. One trick is to put 'old Zenith TV images' in Google. You will get lots of pictures. Find the pictures of yours and some will have the model number stated. From there you can do search on that model number. You should be able to locate manuals, etc.
If you are using a cable box, there should be a setting to change your "aspect ratio". Some offer options such as fit to screen, zoom, wide, etc. see if you can change this setting from the remote. Without knowing what model cable box you have I acn't get more qpecific, but try this first.
Unplug the cable box for an hour,replug it back in.Should get the cable box to reboot to updated the softwares.Might work than,tv seem to have picture,somethings on the screen,words mean ur tv still works.
If you are using a DTV coverter box, you may have changed the aspect ratio with your remote control. look for a button marked "aspect" or "picture size" use that to change size.
If you have a cable box, you may have a similar button.
Or you may find a picture size adjustment on your TV remote.
If you do not have "aspect" button on your remote try going to set up menu and look for picture size.
Older TVs used to have a vertical size adjustment at the back. look in the manual.
If none of the above, you have a biiger problem with the TV internal parts needing attention
It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.
Here is some info I found on your TV:
That resistor is located on the CRT board of each gun. Ususally if an image is predominantly one color then that color gun has a bad 120k resistor on it's crt board.
