Sorry guys total newbie here. I let my son play with my TI-83 Plus and now it is doing some weird stuff. It seems like it is probably just a setting issue, but I have cleared to RAM and returned it to factory settings, removed the batteries, including the backup battery and the issue still happens.
The issue is if I turn on the calculator with the screen clear the illuminated box flashes off on the left side like normal, but now on the right hand side at the top there is are illuminated black vertical line that extend 7 or 8 pixels down. They only appear on that line until the calculations go far enough down the screen where the screen would need to scroll to make room. At the point when the screen scrolls then the entire screen populated with the 7 or 8 pixel vertical lines on evenly spaced grid.
I can hit the clear button and it will return to the flashing box and the one vertical line off the the right side. When the calculator goes to sleep if I have not turned it off upon powering it back up the screen has solid vertical lines evenly spaced going about 2/3 of the screen (width) and some random pixels in the left most vertical illuminated line.
I can't figure out how to insert pictures[/img] but I can email them to someone if I am not explaining the symptoms well.
Appreciate all the help and apologizes if this is in the wrong section
