I have a 62 inch DLP. I have had it for two years. At one year, the lamp blew and the color wheel bearings went out. All was replaced. Now a year later, another bulb blown. I ordered one. I put it in and within a hour, the new one went out! I am looking for suggestions on what could cause this. Maybe the fan?? Also, anyone know of a cheap place to by just the bulb, not the whole lamp?
