For the TI-83 Plus Family, TI-84 Plus Family:

Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect first.

1. Try a new set of AAA batteries.
2. Adjust the contrast by pressing and releasing the 2nd key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
3. Remove one of the AAA batteries. Press and hold the CLEAR key. While holding CLEAR, reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the CLEAR key and then press it one more time to remove the message.
4. Remove one of the AAA batteries. Press and hold the DEL key. While holding DEL reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

Everytime i try to graph it say ERR: INVALID DIM and then below it, it say 1:Quit. i dont know how to fix this and i dont know where to enter the diminsions in. please help me! THANKS!

One of the statistical plots is still active and you must turn it OFF.
  1. Press [2nd][Y=] to open the (STAT PLOT) configuration screen.
  2. Press [4:PlotsOFF]
  3. The PlotsOff Command echoes on main calculator screen.
  4. Press [ENTER] to run command.
  5. Go back to [Y=] editor to edit the functions if necessary, then press [GRAPH].

My TI-84 calculator keeps saying "ERR:INVALID DIM" whenever I try to graph a function. I have used many different equations and tried to reset the scales and stuff in the "WINDOW" but it keeps saying the...

One of the statistical plots is turned ON and you must turn OFF all the STAT PLOTS.
To do so
  1. Press [2nd][Y=] to access the stat plot configuration.
  2. Select [4:PlotsOff]
  3. Command PlotsOff echoes on main calculator screen
  4. Press [ENTER] to execute it.
  5. Return to your [Y=] screen to define functions to graph.
  6. When finished entering functions press the [GRAPH] button.

Everytime i turn on my ti-83 plus the black box covers the whole screen and wont operate no matter what button i press

This really sounds like a problem with the contrast. Try this: turn the calculator on; press the second key, and then press and hold down. This she reduce the dark contrast.
Good Luck

Everytime i try to graph i get an error saying invalid dim on my TI-84 plus calculator

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

TI-84 Plus Calculator: my calculator screen is black everytime i turn it ...

Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key for a few seconds until the screen lightens.

Obviously, if you've gone too far, press and release the 2ND key, then press and hold the up-arrow key.

Having problem with ti 83 calculator everytime i graph it read error invalid dimensions

You must deactivate the statistical plots. If you do statistical graphs, the graphing is reconfigured in a way that happens to be incompatible with regular fuction graphs.

  1. To deactivate the statistical plots.
  2. Press [2nd][Y=] to access the (STAT PLOT) menu.
  3. Press [4:PlotsOff][ENTER].
  4. Calculator displays Done.
  5. You are ready to draw the function graphs.

Keeps plotting the same graph no matter what the function


press y= and see what equation are selected . If one y equal is highlighted than the calculator will graph only that equation , Move the curser on what function you want and press select button it should be in the f keys if not press the more button until it shows up okay

Cannot graph invalid dim error

This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.

If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.

Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.

Graph button won't graph, then it exits and put's a 4 instead ?

It seems that wires got crossed. I suggest you reset all RAM by the follwing steps
[2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]
Ram cleared will be displayed on screen. [CLEAR] to go to the home screen.

If that does not solve your problem, reinstall the OS. Post a question on how to install OS, if you want, or read some of the posts on TI83/84/89 about same subject.

If nothing works, I am afraid you will have to repair the calculator.

Hope it helps.
