Hello all: I apologize for being the upteinth person to write about a green blob on their projector screen but here I go anyway. I have a Panasonic Pt-P1SDU projector, way the heck out of warranty which projects a green, hazy, non uniform in shape, blob on the lower left part of the image. This is a 3 LCD unit as many of you may know. I was in considering a new bulb and bulb assembly for the projector however I have read on this site that it may be a concern with one of the polarizers and not the bulb? Does the bulb assembly house the polarizers as well, if so any recommendations on the new favourite cheap place to buy a bulb online for a discontinued model ? Thanks, Adrian.
