My Experience: This T.V. has been in operation approxamatley 4 years
Problems: This model seems to have a very poor bulb cooling design. the cooling system is easily clogged by dust leading to bulb over heat and premature failure. I would suggest funace filter material be attached to cooling openings along the rear bottom 1/3 of the T.V. This is what I am going to try withthis next bulb.
