My experiences with that camera are as follows:
In the cold, the display turns into dark appearance. That seems in your eye like blinking symbols. If it is getting colder, the display will get totally dark, but it recreates in the warm.
The change of the display after seven years is imho being safe for Nikon and getting money from the customer. I use my F3, since i bought her new in the early 80's, without servicing it or changing the display with excellent results, also in rough conditions.
