AI Thread Summary
The issue with the TI-85 calculator displaying a dark blue screen is likely related to the contrast settings. Users have noted that adjusting the contrast can resolve the problem, typically by pressing the '2nd' button followed by the up or down arrow key. If the contrast is set too high, it may be necessary to reset the calculator by removing and reinserting the battery. However, if adjusting the contrast does not work, further troubleshooting may be needed, as some users have experienced persistent display issues despite attempts to fix the contrast.

Hopefully someone can help me with this problem. When I turn on my TI-85, the whole screen is dark blue (every pixel is dark blue). If I turn it at an angle, I can still see the curser; and performing functions on it still work (when looking at an angle). Has anyone ever had this problem with their TI85? If so, how do I fix it? Thanks.

Thanks very much, it was the contrast.

I tried pressing the 2nd button and the down arrow but nothing changed. the dark blue box is still there.

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
Thread 'ChatGPT Examples, Good and Bad'
I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
