i have a 61″ Samsung DLP that all of the sudden started making loud fan noises last night. we turned it off, let it sit, turned it back on got picture and sound, but the fan was running from low at start up to louder and faster and stayed running loudly. i pulled off the back cover, blew some compressed air into it, plugged it back in, bulb ignites, fan on high loudly, then shuts off. any ideas. oh, I replace the bulb about 3 months ago also.

thanks in advance,
