I have just changed the batteries for my calculator. but the the extreme 2 digits on screen have gone partly invisible. So I cannot see the tenth and zeroth values of a calculation. I checked the ribbon cable..that connects the diplay..it is perfectly fine. I have done the screen test..no go. Resetting the calc doesn't help. Nor does taking off batteries and putting them back on. Any help. Dont feel like throwing it away...but at the same time...repair would cost as much as a new calc.

TenTH = A fraction of a whole, the 'th' tells that.
So, since 25,099 is a 'Whole' number, with No fraction of a whole, or no part/fraction of 1, therefor, rounded to the nearest tenth, it remains the same.
TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
If this doesn't do it, please reply to this post and we can go to the next step.
I am describing the procedure for the CAS with OS version 2.1 But it should work for your calculator.
Turn calculator ON
Press The HOME (House icon) button.
Press digit key 5 to open Settings and status.
In menu options, select [2:Settings]
Use the arrow (right) to open the submenu options and select [1:General]
cursor should be on drop down box labeled Display Digits
down arrow to open the number display format, and select Float 6 (an
appropriate choice most of the time. If you want more digits, set Float
Press [ENTER] or Click to validate your selection.
The drop down box will close.
Use the TAB button to move to another Configuration setting. Pressing the TAB twice will take you to Exponential format.
Use down arrow to unfold the Exponential format menu.
If you do not need Scientific Format, use Normal and validate.
Press TAB several times until cursor reaches OK.
At this point Press ENTER to save Configuration.
This should solve the problem.
I said, this describes the procedure for OS version 2.1. Once you find
out how to enter the setting screen, do as I described above, and do
not forget to validate by getting the cursor on OK and validate.
The F1 key is activated by pressing the alpha (green button) and then the f1 key. If that doesn't work then your calculator may be broken and you might want to check with your warranty to get a new one.
As for the exponent key you can do this by pressing the ^ key and then placing parentheses around the two digit exponent. An example for 2 to the tenth power would be: 2^(10)
Hello, Increase the number of digits displayed. In floating mode the calculator can displyay up to nine decimal digits. And no matter what that last digit maybe, you can safely ignore it. More often than not the extra digits are zeros. As to the value of PI not displaying the 7th or 8th digit, do not worry: most calculations with Pi are precise enough if you use 3.14. Hope it helps.
