Pioneer DEH-P7800MP inverted color issue?

Just got this new head unit. I like it a lot. However, if I use the level meter, analyzer, or gauges with tach, level and battery it seems to change colors intermittently.

Like a orange/white then back to it's normal setting. Like a negative image or something.
This is very annoying and I am not happy about it.
Has anyone encountered this on the OEL displays and if so, how can I stop this?

I thought it was a background issue, but no background to set with the level meters.

Changed from a prior Pioneer head. Used adapter for harness, soldered all my wires right before hook up and everything else works and displays right.
Any insight would be appreciated.

Maybe a loose /bad connection on the face plate? Bad Unit? Try cleaning the contacts? Maybe a loss/drop in voltage for some reason?

Well, I am going to take of face plate and reconnect.
Voltage seems very regular.

Otherwise I call Pioneer.

Thought I caught wind of something like this when surfing and searching,but nothing very clear as to the same issue or not.

Very hard to word it right and fine anything.

Why they would create a setting that inverts the color every 30 seconds and is on by default, I will not understand.
In the manual it read to me at least, that if in a setting area and you didn't make changes within 30 secs it would revert, which I took as an exit.

Anyway, found while searching around.
Seems it is this way on a bunch of their OEL models, if not all.
