My in-dash 7" screen was a little crooked, so I took out the center console to straighten it yesterday. Now every so often when I turn on the screen the image is upside down. It will sometimes play upside down and then after a few minutes go the right way again. At times it is working with no problems.

I tried checking all the connections and cleaned them with electrical circuit cleaner.

Any ideas?

 

How long has it been doing this? Is it just a monitor or is it a DVD receiver? Actually either way I might take it back to where you got it and ask them. I don't think I have ever seen this happen before on any kind of screen/dvd car or home.

 

some screens have a "flip switch" which allows installers to flip the picture just in case they installed it upside down in a headrest... you might have hit that, or it might be loose in the middle, if it's not that, check to see if you rca connections or the plug that goes into the screen is tight, a bad video signal can sometimes make the screen turn upside down as well...
