Small display crack/defect

First of all, I love my new Kemper. Finally I have a tone rivalling my Peavey 6505 with some modified profiles and an FRFR. Will also be using this for fly-in gigs.

I bought the Kemper unseen second-hand (only used 10 hours) to save some money, and I noticed the display has a weird "moire/rainbow/wave" pattern. So I don't know if was like this from the factory. Do you guys think this is a small crack in the LCD itself? When the display is off, the wave-pattern seems to come from a tiny dark spot at the bottom. When I push on or below the screen it nearly goes away. It is a small annoyance since the Kemper is working fine, but somewhat irritating nonetheless. Should I live with it, or try to fix it?

Thanks for your reply. Unfortunately I can't rack mount my lunchbox Strange that even new units have this. Maybe the kemper is vulnerable to normal shipping handling.

That's interesting. I've tried adjusting the screen settings, but it didn't improve. I'll try contacting support then. Thank you.

Hmm. According to http://www.wikihow.com/Degauss-a-Computer-Monitor LCD screens can not be degaussed.

Makes sense. The pattern changes instantly when I as much as touch the plastic/glass. So I think a defect in the protective plastic is messing up the polarization (done some reading )

Sorry for the "necro bump". Here is the scientific explanation: http://en.wikipedia.org/wiki/Newton's_rings
