My samsung mx20 camcorders screen display does not flip anymore when I turn the screen. The display will be upside down if I face the screen toward me to see myself. What is the problem and/or solution?

yes in your display ghraphics. and you might try facing the screen toward the wall.

Try lithium batteries
See my tips Why Low Power Warning For Full Charged Batteries

your cam corder is telling to plug it up when not in use so it can be fooly charged at all times.

The horzontal lines would have to do with the screen unless you see those on the actual video footage on the memory stick.

Fact is I have this cam and know everything about it by experience the issues with these cameras one drop and there basically toast.

Now if there is not horizontal lines on the video itself and the video is clear the issue would be the LCD on the unit.

Let me know and update me with any new information.

SC-MX20 LCD screen is dead.

The hinge unit(with wires) needs to be replaced. If you can DIY, this may help: How to fix an intermittent display LCD on Canon PowerShot S5IS

Windows XP: Flipping the screen upside down and back again


Once, at University, someone had flipped the screens of all the public computers (running on Windows XP) of the English Department upside down. The wallpaper, desktop icons, fonts, mouse-cursor and even the start-up screen...everything was displayed or moved upside down. People could not check out their e-mails or surf or do anything.
To reverse the upside down screen mode, press ctrl, alt and the up arrow (arrows console) at the same time; the screen will probably go blank. Turn off the monitor, turn it on again and the display will be normal again. If you possess a sense of humour or are antisocial, press ctrl, alt and the down arrow simultaneously, turn off the monitor, turn it on again and everyone (excluding the culprit) will be desperate --> upside down! Works for Windows XP Home and Prof.

flip switch is not working or stucked, a loose wire connected to this switch is also possible. you may open the unit and check for it. a pro fix is better.

normally there is a micro switch fixed at the awivl head of the lcd panel. when the lcd is rotated to 180 the switch gets engaged thus turns the image upside down. most probably the switch has worn out.
