I received the replacement lamp very quickly - about 3 days after I placed the order. The replacement installed easily. However, I've notice that after a week, the screen will be fuzzy, not full color, at the initial start up. Then at about 30 to 40 second point (after start up), the screen is fine, (full color - clear, etc). I did have two incidences in the past week where it will start, go about 10 seconds, then shut down completely and the "lamp" indicator flashes. I hit the power button again, and it worked okay. I read other reviews about other lamp replacements and think that the replacement I got may NOT be suitable substitute, and may be stressing a ballast and therefore causing the erratic lamp behavior. If it just amounts to me waiting a few more seconds and the screen is fine, then I'm fine. If it ends up not working after a few more weeks, then I'd say this was a failure due to a inferior replacement part.
