My Philips 60 inch rear projection TV model
Mute the volume and listen at the rear of the unit. You should be able to hear a fan running since these have hot-spots that require some kind of air movment to keep them from overheating.
There are protective circuits that will shut down the power supply once a critical temperature is reached.
The second possibility is the power supply itself; these sophisticated units are very energy efficient but have components in them that age and lose their function over time.
The main supply should be fairly easy to spot; it will have larger components on it, some cylindrical (capacitors), others block-like.
If the fan is running and it is still shutting down, this supply may need repair or replacement.
Look for a part number on the board and inquire at the manufacturer's service center about those possibilities.
Have your model & serial numbers of the set available too.
