Cursor stuck going up.
When I turn on my ti-84, the cursor on my screen is stuck constantly going up. It scrolls all the way through my previous calculations, and then gets stuck at the top when there is nothing else to scroll through. When I click on the down arrow, the cursor appears to flash normally as opposed to rapidly, but I still can’t type anything else into my calculator. Is this some sort of keyboard error? None of my keys are stuck, so maybe it’s soemthing deeper in the calculator.
