Re: bulb
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...

Re: bulb
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.
HTH.
