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

Pixels can die in a TI-89 calculator due to age, physical damage, or a defect in the display screen. Exposure to extreme temperatures can also cause pixels to malfunction or die.
Unfortunately, dead pixels cannot be fixed in a TI-89 calculator. Once a pixel dies, it cannot be revived. The only solution is to replace the entire display screen.
A dead pixel in a TI-89 calculator will appear as a small black or white dot on the screen. It may also appear as a colored pixel that does not match the rest of the display.
This depends on the warranty policy of the manufacturer. Some warranties may cover dead pixels, while others may not. It is best to check with the manufacturer or refer to the warranty documentation.
In most cases, dead pixels do not affect the overall performance of a TI-89 calculator. However, if a large number of pixels die and make it difficult to read the display, it can affect the functionality of the calculator.
