Screen obstruction TI-83 Plus Graphing Calculator

I have a TI 83 Plus Graphing Calculator that has a black liquid mass on the screen. The screen on the right side of the mass is no longer usable. Can it be repaired? It's too expensive for this college student to replace! What should I do?

Hello,
The liquid crystal is damaged. I suppose the screen can be replaced. Check with Texas Instruments resellers (usually academic bookstores): they may be able to tell you where you can have the calculator serviced.

You can post an ad on the college bulletin board

OK for batteries to be dead
But calculator must be alive.

Hope it helps.

How do i turn theta off on the [X,T, theta, n] key on a TI-83 Plus calculator?


That key gives theta when the calculator is set to polar graphing mode. It gives X in the function mode, T in the parametric mode, and n in the sequence mode.

To change the mode, press MODE to bring up the mode screen. Use the arrow keys to move to the fourth line and highlight the desired mode. Press ENTER to make the change, then press 2ND [QUIT] to exit the mode screen.

My TI-83 Plus calculator won't graph anything whatsoever. Did I need new software. Please help me.


First - Are you graphing within the proper window? Hit the zoom button and change it to zoom Standard within the graphing window.

Second - Are you inputting the equation correctly? Make sure you are inputting your equations in a y= format. If possible, please reply with a screenshot of your graph screen.

Whenever i try to link my calculator with other ones it always says error in xmit. no matter what i do


Hello,
Read the following answer from the TI Knowledge Base.
Hope it helps.

How can I troubleshoot an Error in Xmit error message when transferring data between two graphing calculators?

The Error in Xmit error message is returned when a connection cannot be established between two calculators when attempting to transfer data. There are several factors that can contribute to this error message.
• The calculators being connected are not compatible for data transfer.
• The data cable is not firmly connected to both units.
• The receiving calculator is not in receive mode.
• The I/O port on one of the graphing calculators is damaged.
The procedure for connecting two graphing calculators is as follows:

• Connect the data cable to the I/O port of each unit. The cable will fit tightly in the I/O port and snap into place. If silver from the cable is visible, the cable is not properly connected.
• Access the Link menu on each unit
• Place the receiving graphing calculator on "Receive"
• Place the sending unit on "Transmit" or "Send" from the Link menu.

Once the data has been selected, the transfer will commence accordingly.

The data transfer protocols for graphing calculator is as follows:

• TI-73 - Link allows data sharing with another TI-73, TI-82, TI-83, and TI-83 Plus.
• TI-82 - Link allows data sharing with another TI-82.
• TI-83 - Link allows data sharing with the TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-83 Plus/TI-84 Plus family- Link allows data sharing with another TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-85 - Link allows data sharing with another TI-85(To a TI-86. Not From a TI-86).
• TI-86 - Link allows data sharing with another TI-86 and from a TI-85 to a TI-86.
• TI-89 family- Link allows data sharing with another TI-89 family calculator and from a TI-92 family calculator.
• TI-92 family- Link allows data sharing with another TI-92 family calculator and from a TI-89 family calculator.
• Voyage™ 200 - Link allows data sharing with another Voyage 200 and TI-92 family calculator.



If the cable does not fit properly into the I/O port, or if the I/O port appears to be damaged (broken or separated plastic, obstruction inside the port), call 1-800-TI-CARES (1-800-842-2737) M-TH 8:00 AM - 7:00 PM FRI 10:00 AM - 7:00 PM Central Standard Time to speak to a representative or sending an email to ti-cares@ti.com.

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.
