| I have not used my TI-89 in a couple of years, but I just pulled it out and turned it on. The screen is black and I cannot see anything to use it. I tried pressing the green diamond button so I could change the contrast settings, but this did not do anything. I also replaced the batteries, and this did not help anything. I do notice that the black screen flickers every couple of seconds. How can I fix this? |
