My HP 42S Find and Some Questions

There is no realistic way to get to the internals of the 42S through the faceplate, so this probably does not indicate tinkering.

I recommend cleaning carefully with a microfiber cloth and a gentle cleansing solution of the type you might use for a computer screen. Don't clean with a dry cloth, or with a moistened paper towel -- if you do, you will leave fine scratches.

John - Thank you for your feedback. I believe that you interpreted my vague description correctly. I will post some photos in this thread in a few moments.

I have a microfibre cloth and have mild solutions available that I will try.
