What do you mean by "cycling"?
What kind of TV do you have? a DLP or a LCD projection?
Do you hear any strange noise coming from the TV?
Is there any more symptom you can provide us?

Please be more specific...

It's most probably your color wheel, however I recommend to check your fans first and clean them up. If it doesn't work then replace the color wheel.

Search for guides for replacing the color wheel. There you can see where is the color wheel and the fans located.

If your lamp is not well-ventilated the TV turns Off due to overheating, that's why I recommend you to check the fans and air vents first. The bulb shutting down over and over again could also be a ballast issue, maybe is not reaching enough power to keep the lamp ON. However a color wheel malfunctioning could be detected by a sensor which sends a signal to a circuit board to turn the TV off.

So the question would be:
What kind of noise are you hearing?
clicking (ballast), whining/buzzing (colorwheel or a fan) or none (lamp)?

P.S. clean the fans and air vents before turn the TV ON and check the noise.
