Yes, it does sounds like a bulb went bad. Some of the projection DLP tv's there are several different technologies used, sounds like in your case the tv is using multiple bulbs, each under it's own colored screen which the lights project through to make up all the vibrant colors you see on screen. These days the newer rear-projection tv's use color wheels like this.
Sounds like the bulb behind the blue screen may have burnt out and these lights can cost upward of $200, Actually I found some here you can get for your Zenith Rear-Projection TV replacement lamp bulbs for a little over $100
Your TV should have come with instructions how to replace the bulbs and service the TV with regular cleanings and fine tuning, if not you'll need the Zenith rear-projection tv service manual you may be able to find here, I'm not sure which one is for you as you did not post the model number.
These lamps do need to be changed on occasion, here is a page with helpful tips how to make your rear projection tv bulbs last longer.
After replacing the bulb if you need to do any fine tuning, here are instructions on how to get into that menu but please read the warning first. Zenith Rear-Projection TV service mode.
