The mileage is encrypted, but you can copy it from one cluster to another.
The best explanation I have heard for the lcd problem is that something (dust or a water molecule) got between to two layers of the lcd laminates during the manufacturing process. The layers eventually de-laminate causing the problem you are seeing. I'm not sure how the random short you describe would be a factor, but I cannot rule it out.
