Question about Texas Instruments TI-73 Explorer Calculator
I have a TI-73 calculator that has the display showing upside down. There must be a way to fix this! Help!
I have read that to invert the LCD-screen you just flip the polarisation-plate (the plastic film that sits over the LCD display) 180º, that is, upside down.
Did you or someone opened your calculator? He might have reassembled it wrong. Or was it a prank?
If that was not the case, your best change is to reset the calculator and see if it solves your problem.
To manually reset your graphing calculator:
This process should restore the graphing calculator to the factory settings.
