Hi, I just bought a new TI-84 Plus CE calculator, and I was using it yesterday. For seemingly no reason, it randomly blinked and the screen turned a tinted white color, but I could see the OS was still working behind it. Also, anything it tries to say gets overlapped by other horizontal lines.
I'm not sure what I should do, since I already reset it, deleted the OS, and reinstalled the OS, but it still doesn't display things properly. I'm very confused and any help would be appreciated.

Also, sorry if I did anything wrong; this is my first post on Cemetech.

It looks like the LCD controller has failed as a result of a manufacturing defect, since there is no reason for the display to look like this in the OS (& especially, not after reinstalling it), & there is not even any plausible way for it to fail like that as a result of user action. That sort of smearing can result from badly-behaved ASM programs, but if it were a software problem, it would not persist across resets like that. & wiring problems can sometimes be fixed, but this also does not look like a wiring problem (which usually results in missing lines or garbage characters, not smearing).

But since it is brand new, hopefully you can exchange the calculator for a new one.

Oh, okay. I'm pretty sure I can return it since I bought it off Amazon. Thank you!
