Hmm. Gravitech had some smaple code for the Philips controller. That just gives me blue screen, so I've definitely got Epsons. I have two and they are both doing this.
I've tried it on two different 3.3v Arduinos, re-did my wiring. Same results. I can see that even with the backlight powered off, the same thing is happening, so I don't think it's noise related.
