There are several reasons for short lamp life. Inadequate ventilation or clogged cooling fans, a bad lamp driver or lamp ballast (they are the same) and the use of non-original Sony lamps, as the aftermarket replacements are known problem causers. Remember too that the number of times the lamp is turned on and off is a BIG factor in how long the lamp will last.

Something is definitely wrong if you are consistently only getting a month out of a bulb.

Either something is overdriveing the power to the bulb (unlikely) or there is a vibration or something is intruding on the bulb itself.

Good luck and let us know what you find on this.

Lamp burning out every 2-3 months. Fan is okay


Hi anna,
Make sure you have plenty of clearance between the tv and the wall...if not it will keep sucking in the heated air and cause the bulbs to blow.
