Question about Texas Instruments TI-82 Calculator
I tried using my TI-82, which hasn't been used since I graduated in May, and the batteries were dead. I replaced all of them including the backup battery, and now, when I turn it on, all I get is a blank, dark screen (every pixel is at the darkest setting). Adjusting the brightness (2nd + down/up arrow) does not have any effect. What do I do?
Try a hard reset. Take out all the batteries, and while putting them back in, hold down the "DEL" key. Then, turn it back on and you can adjust the contrast by pressing the "2nd" key and the down arrow at the same time. I just got this info. online and it finally worked for me...good luck!
