Question about Texas Instruments TI-84 Plus Calculator
You should make it a habit to clear calculator memory before a new type of problems, Graphing, Statistics, Geometry, Financial etc. It will spare you a lot of grief.
To reset the RAM, press [2nd][MEM][7:Reset][1:ALL RAM][2:RESET] [ENTER][ENTER]. Then Press [CLEAR] to clear the message RAM...
You may have to adjust contrast after the operation. For that you press
1. Press [2nd] and release the key.
2. Press [ArrowUp] to increase contrast or [ArrowDown] to decrease it.
3. Repeat Step1 and Step2 in sequence until contrast is adequate.
Do not mix ArrowUp and ArrowDown: because effects cancel one another. You may have to repeat the sequence several times.
If there are no hardware problems, this should work
Hope it helps. If it does not, well, remember I tried.
