      • Use dollar store 1mm flathead jeweler screwdriver for clutch screws.

    If you don’t have a thin enough screwdriver, you can make one by snapping or grinding the tip off an X-Acto blade.

How does this fix the buttons, I do't want to damage my calculator

Watch for the little clear plastic piece when you put it back together. I think it goes to the inside of the hole for the power connector.

Thanks for this.

The black circular spacers shown at step 6 go on the mounting brackets for the two outermost screws holding the screen onto the mainboard. On the first picture for step 5, if you numbered the circled screws from left to right, those would be screws 1 and 4.

I didn’t have a screwdriver for the clutch screws of the back cover, but a thin, pointed knife tip did the job.

Thanks a lot! Spilled coffee in mine, had to wash all the buttons individually to solve the sticky button issue, worked like a treat.

I have the problem that my TI Nspire CX CAS uses the buttons “Enter, E, K, Q and W” on its own, although i can´t use these. These buttons line up, and i tried cleaning them using the guide here. But I still have the same problem. Does somebody have a clue? Or even a way to fix this?

Andi - Yanıt

Hey! I have a TI-Nspire Cx version. Which screw driver is needed to loosen the screws in step 3?
