The listing, 1 Texas Instruments TI-84 Plus Graphics Calculator, READ as-is has ended.
READ
item powers on, but it seems to have bean damaged somehow internally. Some of the buttons are sticky, I believe some liquid may have dropped on it, but only enough to slow down unit. It MAY just be the small battery, as this unit has bean used a lot.
The unit worked fine for a long time, until one day it was slow, and kept showing the message seen on picture #2. I was able to pass that screen to the main screen to work, but the buttons are very slow to appear on screen, and some buttons will not even work sometimes.
As far as the listing is concerned, the item is broken, as-is, for parts and repair, non working.
