Hello,
Press [CLEAR] to erase the screen. If that does not work reset the RAM
Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Then press [CLEAR].
If these steps fail, you should read the article.
Hope it helps.

### My sons 10" Zeepad has a flipped/ mirrored screen, even the touch screen buttons are reversed.how do I get the settings back? I've restored several times..& it won't reset or restore to factory..?

Try pressing "Ctrl" and "Alt" at the same time. Whilst holding these 2 buttons down also press one of the arrow buttons. The arrow down flips the screen upside down, the up flips it right way up, the right to the right and left to the left. This is a great trick to mess somebody's screen without doing any damage. If they don't know about it, it really messes with them......as you my well have found out. Good luck.

### Lines across my tv where the picture is reversed

You have bad capacitors in the vertical deflection. And you will have to resolder the vertical IC as well. Replace the caps in the area of the vertical IC. Find a TV tech or hobbiest to do this!

### Flipped\upside down screen on my compaq

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.
