The lamp must be reset when replaced. Check the owner's manual on how to reset. I had a similar problem and I was instructed to reset my lamp with a few TV remote control functions.

Testimonial: "I have to say this is the 3rd lamp I have replaced in my TV in the 5 years of life. It is used extremely heavily over the years and never before have I had to reset the lamp.

I therefore now have a Color wheel on its way."
