Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

Configure Windows "video" properties to have Windows "rotate" the picture 180 degrees, i.e., make Windows produce "upside-down" output, and the screen will "flip" that output.

When in file viewer mode you can rotate pictures, this is in the manual and may be the cause.

Scroll dowm from the top left corner, and you will get the option to rotate screen.

This is a feature not a bug...The LCD is designed to flip the picture when you rotate the screen. This is so that you can see what you filming or be in the picture and see yourself filmed. I can't remember if it flips automatically or not. But, I would first try inverting and reverting the LCD screen to see if you can get it to detect orientation, then check and see if there is a setting to manually set the orientation of the LCD instead under the menu options.

Read the setup manual more closely, the answer was very vague and a person has to pay close attention to the pictures. Found one picture that showed the menu with "flip" displayed on it.

There's a button on the original remote control that does exactly that:
