these displays ared l.c.d. displays and what happens is over time the vacuum pack on the crystal element ruptures and get air in the tube and that part of the display is ruined permanently.I'm not sure if your saying that there are pieces missing or if the whole display is blank. If there are peices missing the only way to fix it is to repkace the instrument cluster. If they are blank it is very likley it is either the backlighting bulb or the dimmer switch. If you take a blanket and cover your display and can see the display very dimmly try replacing your back lighting bulbs- hopefully it is just your backlighting because the clusters are about 1,000 dollars and have to be special ordered with your mileage engraved in the new unit.

Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!
