oLED screen stuck

I just got one of the oLED displays. I got it working pretty well last night and now it booted up with a screen saver that won't go away. I've tried reprogramming and reseting. It always boots up to a scrolling screen that has an advertisement for 4D systems. There is a reset pin that the instructions say not to use, could it have something to do with this?

    No, I think you might be mis-programming it. You might momentarily connect the reset pin to Vss and the oULED will reset, and go through the 4D systems advertisement/screen saver. Mine boots on with a white line slightly right and wont go away untill I reset to Vss.

    There is a jumper on the back of the display. If this is shorted it forces the display into demo mode. The jumper block should not be shorted. Please check that. Take care.
