    • If the screw is not turning, do not force it. This can strip the screw. See the How to Remove a Stripped Screw guide if the screw is already stripped.

    • Using the #00 screwdriver, unscrew the six, 6mm Phillips screws.

    • Use the spudger to pry into the space between the blue back cover and the white body to take off the back cover.

    I didn’t have a spudger but a flat 3/32” jeweler’s screwdriver worked just as well. Also, the battery slides out the side, nothing to undo. I slid it out using a jeweler’s screwdriver. (Don’t touch any electrical components or traces with the metal tip.) If you’re not sure the battery is good, turn the unit over and see if there is anything displaying, or run a test operation like 2 x 2 etc. to check before putting the back into place.

    • Using the #00 Phillips screwdriver unscrew the two, 3mm Phillips screws located near the top of the calculator.

    • Lift the metal plate from the battery and set it to the side.

    • Use the spudger to lift the battery up from the black holder.

    Funktioniert beim 30X Pro Multiview gleich?

    Is a spudger really necessary. I don't have it, just the phillips 00 screwdriver. Do I need to go out and buy one of these?

    You can just use a fingernail to open it.

    • Put the new CR2032 battery in. Never insert a different type of battery!

    • Reverse the steps 2 and 1.

    And if the calculator doesn’t turn on if you press “on”,

    press the “reset” button on the back.

    my TI-30XS battery was mounted directly onto the circuit board under a metal clip, the black battery holder doesn't exist at all. Anyway the battery is the still the same CR2032.

    • Using the Phillips #00 screwdriver, carefully remove the two 3mm screws holding the screen in place.

    • Be sure to pull the ribbon cable, so that it only disconnects from the larger green board.

    • Gently lift the screen up from the front of the calculator, carefully disconnecting the ribbon cable from the larger green board.

  7. XS2SK3TixO3L5v3J

    • Once the screen has been removed, it should still have all connecting wires and the ribbon cable attached to it.

    • After the screen is replaced, you will have to re-solder the ribbon cable to the motherboard.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Where can you find a replacement screen for this calculator?

Really the only way to find a replacement screen is by just buying some broken ones(but with a good screen) off of Ebay

dows soldering the ribbon cable back actually work?

IMO this does not appear to be a repairable or serviceable part. Upon removal, the soldered or self-adhered conductors on the ribbon cable usually separate and tear off the ribbon cable, and are left stuck on the board. Unless you very very very very carefully scrape them off or they can be de-soldered, there's no replacing the display. The same problem will occur in reverse when trying to remove a good screen from a donor calculator, which is almost as expensive as the actual calculator (10-15$ USD). It's possible... just not sure it's worth it.
