Odometer LCD display not working.
 

So I was going to Tag and Register my 1995 C280, however I went to get the millage and the Odometer doesn't show anything. It's just black. I've tried replacing the bulb and even shining a flashlight through it while it's on. But it just stays black. Is this a common problem, or is there a way to repair it, also is the millage kept in the cluster or in the ECM somewhere?
