My bulb on my mitsubishi keep blowing out - Mitsubishi WD-57733 57" HDTV

SOURCE: Mitsubishi projection tv keeps blowing bulbs! Every 6-12. Months. What is causing this tv to blow bulb?

bulbs normally fail from, overheat, loose in fitting or over voltage
if it is a screw in bulb then the problem may be from a loose earth (ground ) connection in the holder ( arcs just like a welder and that cause over voltage and surges to the bulb)
if it is a ceramic holder there should be a brass strip that rubs on the thread of the bulb as you screw it in
remove the power cord from the wall socket and bend the strip out to increase the load on the thread
screw in the bulb and every so often make sure that the bulb is tight
always make sure that the cooling fan (if there is one ) for the bulb is running at full rpms before ,during and after the unit switches on/off
