TI-36X Pro Solar Panel Replacement

Remove the calculator's protective cover.

Place the calculator face down.

Using a Phillips #1 screwdriver, remove the six 6mm screws from the back of the case and place them to the side.

Start from the notches on the top edge and use your fingers or a prying tool to carefully pry the back cover from the calculator.

Use a Phillips #00 screwdriver to remove the two 7.5 mm screws holding the battery cover to the case.

Use your finger to move the battery cover to the side.

Use the flat side of a spudger to remove the battery by lifting the bottom edge.

To detach the solar panel, use a Phillips #00 screwdriver to remove the 4.5mm screw that connects the solar panel to the calculator.

Once the screw has been removed, you may lift the top of the black solar panel cover with your finger and gently pull away from the green circuit board.

Turn the black cover so the solar panel is facing you.

Insert the flat end of the spudger between the solar panel and the black cover at the corner where the red wire connects.

Carefully slide the spudger all the way underneath the solar panel until it detaches from the tape.

De-solder and disconnect the red and black wires from the solar panel.
