It sounds as if the lamp has failed possibly due to a failed cooling fan (the fan should be the first thing to come on). here are the links to the user manual if you need it;
It may be worth trying to uninstall and reinstall the lamp, but usually these fail internally rather than having bad connections etc. It is often obvious when the lamp has gone from a visual inspection.
If the lamp has failed, when you replace it, make sure the fan comes on - if not then turn off instantly and investigate further.
One other possibility before buying a new lamp, is that the lamp compartment cover may not be properly fitted. This will interrupt the power, so I am assuming there is a microswitch or similar that the cover or the screws that hold it should contact. Possibility is that the cover is badly fitted, or a small piece of the cover has broken, which would normally contact the switch, or the switch is faulty - if you can see the switch then a continuity meter will easily test the switch. Also check that the lamp unit securing screws are properly tightened, they also may stop the TV powering on.
Please ask again if you need more help with this, if you are unsure then a photo of the inside of the lamp compartment and the lamp itself may help :)
