Ripped screen on Zenith 52"Tv

Replace the light engine.

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.

Goto your menu - using the original remote.

The Lamp will no cause any color distortion. The "Replace Lamp" message comes up after a certain amount of hours after watching the TV because the lamp only last a certain number of hours before needing a replacement one.

It sounds like a light engine problem. There is no quick fix, you need to replace the whole light engine which is very costly (light engines usually run at least $500) and time consuming (need to take whole TV apart to replace part).

Components in Power supply are bad most likely a 35v 100ufd capacitor if not then your Flyback transformer is bad

Bulb must be replaced before viewing will continue.

you need new picture tubes, they are expensive, big screen tv life is about 10 years

I just found the solution on another model of Zenith TV. Hold the enter button down on the TV and the MUTE button on the remote. In approx. 5-7 seconds a screen will pop up asking if you want to reset the lamp timer. Hit the bullseye button in the middle of the arrows and it will reset. Worked perfectly.
