My 3 year old P1500 suddenly doesn't want to start up anymore. It gives a clear image after startup and then flickers and shuts off. 
Most of the time it does not show a lamp error. Sometimes it does. 
I have already changed the lamp, but the new one does the same thing. So I dont think it is the lamp.

Does anyone here know what the problem might be?
