Title:

Replacing the lcd with a different one.

Text:

I have a TI-84 Plus CE-T With fancy broaken LCD rainbow colors on the screen. I took it apart and after inspecting the LCD, I couldn’t find any part number markings that gave me any results on searx, aliexpress or ebay. I figured that this screen is probably using a somewhat standard protocol and pinout. Therefore I was wondering if I might be able to replace it with a simularely specced lcd from aliexpress with the same amount of pins on the connector. I ended up finding this part

The connector looks right and has the right amound of pins allthough it is upside down and on the wrong side, I could probably just fold the flat flex connector though. Does anybody how likely it would be for something like this to work
