PT-56DLX25 Bulb in, no picture shuts off.

Just picked this up for 25$, can't complain right? Has a new bulb in it. I turn it on, no picture, and shuts itself off after a bit. The power light is flashing green the whole time, and there's no lamp indicator light on. Fans spin up and everything, my laptop recognizes it as an output source for hdmi. I have the ability to take it apart and fix it, would just like to know maybe what I'm getting into before I pop it all the way open. If anyone has had this problem and I can avoid opening it all the way.

Also. Have it almost entirely apart now. Thinking its in the projection system.
