BBB LCD3 bad picture

I just received my LCD3 cape, but the LCD is not showing a nice picture, it looks like every second line is permanent white.
The second time I powered the cape, I got a brief period of about 1 minute where the LCD was fully functional = good contrast, all lines in use. I was not adjustin any settings, neither to make it work not when it stopped working again.

The cape is a LCD3-A2
The BBB is running ‘Cloud9 GNOME Image 2013.06.20’
I have tried with both USB power and with a 5V 2.5A supply.

Any fix, or is this an RMA.

I suggest you contact the supplier on this one and get their help. Sounds like it could indeed be faulty.
