people.......please let me save you hours and hours of time and frustration. Learn from all my mistakes!!! Buy your lamp from projector lamps .com. They are extremely professional, prompt and very detailed. They will ensure that you get the right lamp for your tv the first time!!!!!!!!!! Ordered from a competitor (jasper Electronics) and that was a costly and huge mistake. competitor bulb did not fit at all even after they assured me it would. !!! Tried and tried and tried and tried some more and got very irritated. The competitor said it had to be my tv, I explained it was not a problem with my tv. Then competitor wanted me to change out lamp box by using a diagram. Got frustrated and sent this competitor their Chinese lamp bulb back. Then had to hassle them to refund my money and they kept 20 bucks so it ended up being much more expensive and full of problems trying to save a few dollars. Immediately ordered a new lamp from projectorlamps.com and received it the next day. opened the box and the bulb slipped effortlessly into the back of my tv! A Perfect fit. Thank you projector lamp . com, I will never use another competitor again. Lesson learned. RN
