Einleitung

If nothing is working at all on your calculator and nothing you have tried has worked, you may need to replace the motherboard. If the screen is cracked or damaged, you will need to replace it. This guide will show you how to replace both the motherboard and the screen, because they are attached and cannot be easily separated.

Where can I buy the screen/motherboard?

Tim van Steen - Antwort

Did you find out where to purchase the screen/motherboard? Having trouble finding it online.

Thanks.

Jacqueline Kennedy -

any update on where to fin a motherboard/screen? i found a youtube video which showed how to replace the screen flex, by soldering on new wires, and have read that the only way to get parts is from another calculator, can anyone confirm this?

Yeah - I can't find one to buy either. Your instructions look great though.

I don’t believe you can buy the motherboard anywhere. However you can salvage them out of other damaged calculators.
