My 2009 Prius, 121,000 miles is having display screen problems. The screen displays fine for climate, radio, disk, trip info, settings, etc. However, it when I try to switch to the energy screen, all I get is a black screen. Also, the other screens, while they display fine, will also go black after about 10 seconds or so. Im seeing nothing in the manual. Any suggestions out there? Thanks, John
