Somone else posted this solution on a different thread and it worked for myself. You turn the calculator on. then repeat "2nd up arrow" to get the darkest setting. let the calculator sit for awhile on the darkest setting. Then clear the screen with the "clear" and turn it back to regular contrast settings. I had to repeat this twice but it now works fine.

Open it up and remove the protective metal.
