My ti-86 screen is black is that normal. I have not used it in years, but i put fresh batteries


Hello, First of all no; it is not normal for your screen to be black. How can you enjoy the wonderfulness that is Ti with a dark screen. For the solution; it sounds like your contrast needs to be adjusted. Hold 2nd and down. The screen should lighten. If it reaches about where you can not see the cursor, then press 2nd and up and this will darken it. Hope this helps; Happy Calculating
