I have one of these, but the LCD is bad (terribly faint). How would I go about fixing it?

- lalalandland 6y agoHere is a video about replacing the screen. Also see video description for where a screen can (could?) be bought. https://www.youtube.com/watch?v=Oa630UVaWp0 https://www.youtube.com/watch?v=Oa630UVaWp0 Edit: Seems to be for a different version
- opencl 6y agoThe most likely culprit for display issues on these old calculators in my experience is the ribbon cables. You can take a multimeter and check the resistance of each connection, if any of them read too high you can solder a thin wire in parallel with it. Or it could be the contrast potentiometer giving too high of a resistance, you can try cleaning the internal contacts or replacing it.
