Normal or sign of failure?
What's the ambient temperature in the room?
Fluorescent tubes, like the ones that comprise the backlight, don't achieve full brightness immediately, especially at lower temperatures.
A great illustration of this behavior is provided by CFLs.
But, it shouldn't take longer than a couple minutes at most to present a picture this isn't noticeably or abnormally dim.
