Discussion Overview

The discussion revolves around a problem with the TI-85 calculator, specifically regarding the screen displaying a uniform dark blue color. Participants explore potential causes and solutions related to screen contrast settings and reset procedures.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes the issue of the entire screen being dark blue and asks for help in resolving it.
  • Another participant suggests that the problem may be due to the contrast being set too high and provides a method for adjusting it based on their experience with a similar model.
  • A third participant confirms that high contrast can cause this issue and mentions needing to reset the calculator by removing a battery to fix it.
  • A later reply expresses that adjusting the contrast did not resolve the issue, indicating that the problem persists despite attempts to fix it.

Areas of Agreement / Disagreement

Participants generally agree that the issue may be related to contrast settings, but there is disagreement regarding the effectiveness of the suggested solutions, as one participant reports that their attempts to adjust the contrast did not work.

Contextual Notes

Some assumptions about the functionality and similarities between different TI calculator models may not hold true, and the effectiveness of the proposed solutions remains uncertain.

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.

Maybe the contrast is too high. On my TI-80, which I assume is more or less the same, you adjust it by continuously pressing the '2nd' button followed by the up or down arror key.
 
I've had this happen too. Like Delta said, it's the contrast. The one thing about my TI-85 is that if the contrast goes all the way to the max (like yours seems to have) I have to pull a battery to reset the calculator. Once I do that it is fine.
 
Thanks very much, it was the contrast.
 
Ti-85

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