2002 computer information display

[William B.]

When first turn key on, the computer information display does its display and
then goes completely blank. Shows no mileage or nothing. Anyone know
what the problem is?

Thanks

Well when you turn the ignition key to the on position, the DIC will display 'Corvette by Chevrolet' and then since the different monitors and sensors are not registering any fresh data, the screen remains black. Now once you turn the key to 'start' and the engine fires up, then you see on the HUD display and or the DIC things like RPM's Oil Pressure, Coolant temperture, transmission temperture and so on.

Thanks for responding Jim, but even after the engine is running and we
are driving down the road, the display is blank (black). It was working
fine when we drove it last a couple of weeks ago.

Did you check your dimmer switch to make sure you're not turned to dim?
Also:

Scroll through your settings on your DIC to see if you are paged to a blank screen.

It is possible that the circuit board is the problem. Check your fuses, although I don't believe the DIC has a dedicated fuse.
