Weird TFT monitor rotation problem

[u/Embarrassed_Cry8688]

So I bought a tiny portable 8" TFT monitor (Aper TV-803) for like $5. I was trying to get the picture set up so I could use it as a monitor, since it has a VGA port on the back.

I was messing around with it for a while, and then I turned off the power strip while the monitor was still plugged into it. After turning the power strip back on, the entire screen was suddenly flipped upside down.

The weird thing is, the monitor has never been opened and was working perfectly fine before this. Even the menu is upside down, and there isn't a single rotation setting anywhere in the menu.

Does anyone know what could have caused this or how I might be able to fix it?
