Probably have to replace the instrument cluster. It could be the stepper motors, but they usually don't all fail at the same time, unless the board they are mounted on has a problem. If the car is more than 10 years old, the instrument circuit board may have failed capacitors on it. Google "bad caps" to find out about that.

When I replace the instrument cluster is it necessary to program it?

...since that includes the odometer, you may need to do that.
