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.

It seems the problem is on the lcd. technicians usually use soldering iron to apply heat to the cable connecting the lcd to its mainboard.

Here are the capabilities of the Casio calculators.

The screen captures may not look like ones taken from the FX-7400G

plus display but the instructions are accurate.

In stat enter the values in List1 and the frequencies in List2**(if doing paired variable statistics)**

Press the key corresponding to the CALC tab

Press the 1-var tab and you get the results as seen on the screen with title 1-variable.

Other screens show some two-variable stats or regressions.

Use you knowledge of sample standard deviations and

population standard deviation to select which is relevant to your case.

They are given by xsigma-n and xSigma n-1

Hello,

I am sorry but I do not quite understand by the LR showing in the display.

For the FX-115ES, the only instance where the L and R appear is in the solutions screen.

When you use the Solve( function, the calculator searches for the solution. When the solution is found, the screen displays

(actual exemple)

**Y=3*X^2-2**

X= 0.8164965809

L-R = 0.

The L-R =0, shows that the precision of the solution, Left member -Right member =0.

To clear the screen you press [AC].

Hope it helps.

Yeah I had the same problem, you need to open your calculator and check if all the screen cables is alright, i had just put sellotape on the back of the screen from inside so that the screen hold better, and it works for me if for you not maybe something broken in the schema but try it. The thing I know for sure the problem is in the screen or from where it get the data the schema. Tell me if it's working

I have found the company site for you. Here it is. You can send an inquiry to them.

But from the looks of it, I believe this calculator is rebranded Casio FX-82. An even if I am wrong, you should still be able to make good use of the Casio FX-82 manual to understand how your calculator works. Scientific calculators do not differ much from one another.

Here is the link to the Casio FX-82 manuals.

Turn it on, hit "shift", "set up", then "2". Puts the calculator in Linear I/O and gives yo decimals! It will stay in this mode 'til you change it.
