When I power-on my 3300mp the little screen says "Warming Up". After a few minutes this message changes to "3300mp". Then after a few seconds it reads "Lamp Failure". I bought a replacement lamp, installed it, and STILL.... it does the same thing. When I first power on the projector it beams out a little light then after the "Lamp Failure" message, my whole unit freezes. The only way I can power-off is by disconnecting the cord because the power button doesnt  work when I press it. I can't access the OSD screen or anything. Somebody help please; thanks in advance.
