Nspire Screen rotated 180 degrees
Dapianokid:
The coolness level of this glitch is exceeding 9000 as we observe and ask questions. I can only think that I'd be a little overwhlemed if in his position, knowing practically nothing about what you guys are talking about and just wanting help xD
Z address?* Dapianokid wants to know what that is
Eiyeron:
IMO it's some adress pointed directly in the display driver. For instancr there is a z-a that shift the displayed VRAM up/bottom without editing any pixel.
Hooloovoo:
I looked at the documentation of the primecell LCD controller, and there isn't a bit that does that in the display driver. It must be flipped in the screen buffer, or something odd is happening.

I know this is a very old post but I had this happen to my CAS calc and fixed it so thought I may as well chip in.
Tried everything mentioned in the thread, took the battery out for >10mins, formatted and updated to latest OS, and gave it a few good hits in case there were any loose connections.
None of these worked so I took it apart. Noticed there was a small speck of oxidization or something on the connection from the screen to the main board. got rid of the speck and now everything is back to normal, no more flipped screen.
Not sure if there was a connection between the two but worth checking out if you're having this issue.

Pretty cool that you were able to get yours fixed. Thanks for sharing. :)
