8591e spectrum analyzer takes 5 minutes before display comes up

I've got an 8591E spectrum analyzer that works fine except for the fact that it takes about 5 minutes after turn-on for the display to come up.  

The first few minutes after turn-on, the display is completely dark, then when it starts to come up, the geometry is expanded, then it shrinks down to the proper display size.

If the analyzer if off for less than a minute or so, the display comes up quickly.  If the analyzer is off for more than five minutes, it takes 5 minutes to come back.

Any suggestions would be greatly appreciated.
