How to replace the crt on a phillips rear projection tv

Is it a LCD or a CRT Phillips TV.
If LCD - could be the lamp just getting old (lot of hours on lamp). Could find the model # of the TV and do a Google search of the TV Model # to find a replacement lamp. If its an older CRT Projection TV the tubes may be getting old and unable to illuminate/glow as they used too! Much like a old set of headlamps on a car.
