Question about Texas Instruments Office Equipment & Supplies
Can i somehow use warranty and they replace it for free?
That is asking too much. The calculator is not supposed to take a bath no matter how short. Try to have it repaired, if at all, but do not expect that to be free of charge.

I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.
Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.

SOURCE: I downgraded my TI-Nspire's OS
I had this same problem myself and I had to look everywhere to find a solution. You will have to remove the current OS from your device. Heres how.
I couldnt use option 2 for some reason and had to use option 4 (complete format, luckily I had backed the files up earlier) but once it was reformatted the device showed up in the software and told me to update the OS. From here you just install the latest OS as you would normally.
The problem with what you and I did is that previous OS versions (1.7 in my case) dont support the keypad, you may be able to use the older version with a different keypad but I'm not sure.
Anyway, I hope you can fix it, good luck.
