One of my screens shows the video upside down

Hi Randy, it sounds like you have a timing control board from another model or series TV, they can look identical but have different programs in the processor IC, if this isn't the case then something was changed in the service menu while the set wasn't operational. We've seen it happen in our repair center, we replace a board with the correct part but the picture is upside down or reversed, had to have happened when the owner was pushing buttons without a picture on the screen

Jay there should be a External Switch on the Screen,Try looking ttech

When the viewport is completely flipped around so you can see it when you are looking at the lens, it automatically flips it upside down so it is right side up to the viewer. Make sure it is locked into the correct position to prevent this from happening.

Hope this helps

Hi.

You may have accidentally hit a sequence of keys and now your Windows screen is upside down.

Press Ctrl + Alt + arrow (left, right, up or down) to rotate the screen to the correct way.

Check for the drivers ,might driver version is not perfect.Reinstall drivers for your cam

The orientation of your projector can be setup from the "Option" menu. You may need to select the "FRONT" and "CEILING" options to display the correct orientation of the image.

Restart the computer, press F8 as it boots and select Enable VGA from the boot menu. This will set the video settings to default.

Try connecting it to a different computer. If it's upside-down on another computer, then the panel is probably mounted upside-down. If it can be removed from the stand, remove it and see if it can be mounted the other way.

If it's correct on another computer, then your graphics settings are incorrect. Assuming you're running Windows, go to Display Properties, Settings tab, click Advanced button, look for a tab describing your video adapter (usually ATI or NVIDIA). In the video adapter's setup there is usually a Rotation option. The rotation option may be set to 180-degrees instead of Normal or 0-degrees.

The screen need to e calibrate, most factory service center could do it. Goodluck.
