My TI-84 will graph but it will not show me the table of values. It just shows up blank.


Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.
To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

I just got this calculator and i was looking at the features and the screen suddenly turned black and every pixel is filled in.


It may be that the screen resolution has changed. To change the screen resolution, turn the calculator on, pres the 2nd button and then hold the down arrow. If this is the problem, the screen should lighten up. Similarly, you can darken the screen by using the up arrow.

My HP 48GX just displays a black (all pixel) display screen with one vertical stripe down the middle. I tried reset button and now it displays 2 vertical stripes (the new one divides the right half in...


I just had this exact problem so I reset the memory as instructed below. Know I am back in business. Memory reset A memory reset will return the HP 48 to its factory-default state, which will erase all stored user memory. Use this feature very carefully.
  1. If necessary, turn the calculator on.
  2. Press and hold the ON+A+F keys simultaneously.
  3. Release all three keys at the same time. This should cause the calculator to display the message "Try to recover memory?"
  4. Press the A key to attempt to recover memory or the F key to erase the user memory. When A is pressed, occasionally the objects in memory are recovered in new sub-directories of HOME labeled D.01, D.02, et cetera, although there is no guarantee that all of the variables will be recovered. Pressing the F key will cause all information stored by the user to be erased from calculator memory. This will also affect any RAM card that is merged with main memory. If the card is not merged or it is write-protected, it will not be affected by this reset.
Hardware symptoms and solutions I. The display screen has a blue/purple blotch of color, even when the unit is off The screen is damaged, and the calculator requires service. Please contact HP . II. All of the pixels on the screen are lit (blue)
  1. Try to adjust the contrast by holding down the ON key and repeatedly pressing the [ - ] key.
  2. If the screen is still dark, try to halt the system using the keyboard.
  3. If this does not correct the problem, try to reset the system using the reset hole with the batteries removed.
  4. If this does not work, remove the batteries and let the unit sit for 48 hours. After 48 hours, replace the batteries. If the problem persists, attempt a memory reset. Although removing the batteries for 48 hours should erase the user memory, performing a memory reset will ensure that the calculator is reset to its factory defaults.
  5. If the problem persists, the unit requires service. Please contact HP .

For what GT used ?


Somehow, I have a hunch you are not talking about the FX-115ES or any other scientific calculators. The G-T feature refers to the Graph to Table functionality of graphing calculators:From a graph you generate a table and have then displayed side by side on the same screen.

Dead Pixels?


I've heard that if you press on the dead pixels with your finger for a few seconds, sometimes they go away. I've also heard if you get a damp cloth, turn the screen off, press it on the dead pixels, turn the thing on, and remove the cloth, they might also go away.
