Glad I'm not the only one. I was pulling my hair out trying to figure out what I was doing wrong. I notice this problem mostly when the screen is idle (characters sitting on the screen and haven't changed for a while). Is that what you see?

If there isn't a software fix for it, I guess I'll have to use an output from my ULN2003A to take care of the power cycle.
