SUMMARY

The discussion centers on the potential causes of pixel failure in a TI-89 calculator, specifically addressing whether age or heat is responsible for the malfunction. Users noted that a row of pixels disappeared after three years of use, suggesting that prolonged exposure to high temperatures could lead to such issues. The consensus indicates that if the calculator was left in a hot environment, such as a car, it may have contributed to the pixel failure. Ultimately, there are limited solutions available for this type of hardware issue.

A whole row of pixels just mysteriously disappeared while I was using my calculator. Age maybe? It's about three years old.

If they get too hot this can happen...did you leave it in your car on a hot day by chance?

there is not much you can do about it. sorry...
