Unfortunately, TI doesn’t offer any repair centers anywhere. If your calculator is still within warranty they will replace the unit, but if it’s out of warranty then you’ll have to pay for a new one. Your problem likely has a very easy fix so there shouldn’t be any need to contact TI yet.

# This may be as simple as the contrast being too low. Turn the calculator ‘on’ as you normally would. Now press [2nd] then the up arrow multiple times. After a couple times of pressing [2nd] and the up arrow, the screen will appear again if the contrast was the issue.
# If that’s not the issue then, as jostewcrew suggested, try changing out your backup battery. There’s a guide for accomplishing that here: [guide|11094]
# If it still doesn’t turn on then there may be an issue with the screen itself. If you have the link cable that connects your calculator to your computer, install ‘[https://education.ti.com/en/software/details/en/B59F6C83468C4574ABFEE93D2BC3F807/swticonnectsoftware|TI Connect]’ ('''Not''' ‘TI Connect CE’) on your computer then connect the calculator to your computer. (The port is on the bottom of the calculator and looks like a headphone jack). If your computer detects that your calculator is connected, then there’s something wrong with the screen itself. Likely the ribbon cable is degraded and needs repair. There’s a guide for fixing that on a calculator forum called Cemetech: https://www.cemetech.net/forum/viewtopic.php?t=5161
# If your computer still doesn’t detect the calculator (make sure it’s on!) then there’s a more serious hardware issue and may not be diagnosable or fixable.

Hopefully you don’t need to get past step 2 but I wanted to cover all bases just in case. Good luck!
