Question about Texas Instruments TI-83 Plus Calculator
Schematics to repair a TI-83 caculator
Posted by Anonymous on
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.

The solution for the problem is simple. When you use the calculator to
create statistical graphs, it is configured to accommodate the specificities of the
problem. However that configuration remains set after you terminate the
problem. So when you try to use the calculator to do other problems it
uses the stored configuration parameters, which may be incompatible
with the new problem. In particular, list of paired-variables must have the same dimensions: There must be the same number of elements in each list.
To make a long story short, you should make it a habit to reset the Ram every time you want to do a new problem. If for reasons of you own you do not want to reset the Ram, you can prevent this type of errors from occurring. This is how you do it.
