Hi,

So my calculator is stuck on the menu screen, and even if I take out the batteries and put them back in, it still shows the menu screen. NO keys are working, and I cant move in between the menu. Everything is stuck and no way to get it back to normal.

I tried changing batteries and resetting using the reset button, but nothing is working!

This is how it looks like, got the pic from the internet:

So basically it stays stuck here, and nothing happens, no keys work.

My calculator was not used for a month and now when I try it does not work.

Please help on how to fix this.

Does inserting the USB cable (while having the other end attached to your computer) do anything?

I have not tried that..will it make a difference? Can I flash stock factory file on the calculator using computer?

Yes you can, and if you insert the USB cable it might auto-wake and let you use the keys.

Otherwise, there is something else you can do:


- Press F2+4+AC/on+RESTART at the same time and hold all keys for a few seconds
- Then release the RESTART button (still pressing F2+4+AC/on) and wait a few seconds
- Now press 9
- And then press × (multiplication)

It could also be a display driver issue, Have you ever taken your calc apart? at school we took a 9860 apart and accidently damaged the display driver, it got stuck like that until tha calc died, and then wouldnt turn back on after replacing the batteries

Not sure what happened to the formatting on that post :wacko:
