I had an air bubble between the screen on my At Pro and the decal that is on front of the screen. I obtained a new decal from my Mder dealer and proceeded to peel off the old decal. I used a hair dryer to heat up the decal before doing it but it did not go as planned on the first attempt. The decal came off but the thin plastic backing on that decal stayed on the screen. You can see the result on the first pic, the plastic film was still on the screen and the two screw heads were still covered with this plastic.
I heated it up again and the thin plastic film came off very easy to leave a fairly clean screen with no glue residue and the two screw heads were exposed.
As long as I had this off, I unscrewed the two phillips screws and pulled the screen out of the black control box. The computer controls are only about a 1/4 inch thick and attached to the back of the front screen. Inside is a large cavity with the battery compartment and the two ports for the coil and head phone connections. There are two electrical connections to the computer board that I unhooked for ease in laying the computer board flat so as to take a pic of it. There is a third wire to the computer board that I did not unhook.
You can see the four phillips screws on the computer board and they secure the computer board to the front plastic screen. There was some dirt in and around the push buttons(see in pic) and separating the computer board from the plastic screen enabled me to separate the push buttons from the plastic screen and really clean up the plastic screen and the push buttons.
Also, around the outside of the plastic screen is an O-ring set in a groove which serves to seal the unit from water entering. Took out this O-ring and cleaned it up and then applied a thin coat of silicon grease to this O-ring before replacing it in that groove. This silicon grease also makes it easier to slide the front screen back into the black control box.
Used a hair dryer to dry everything off before putting it back together again.
I used soap and water to clean up the plastic screen before replacing the new decal-looks brand new now. First pic is screen with the plastic film still on it. Sec pic is screen with plastic film off and showing the dirt around the push buttons. 3rd pic is the cleaned up screen. 4th pic is the computer board taken out of the control box.
