I am trying to get a GLCD and a TouchScreen working together. I’ve got them both working separately just fine. But, when I put them together, the GLCD goes blank expect for a thick line at the top (like the “liquid” is pooling at the top of the screen).

I haven’t had a lot of time to fiddle with it, but if the TS is held above the GLCD, there isn’t any problem. Even just propping one edge on a pencil, between the black GLCD bezel and the TS keeps the problem from occurring. But as soon at they “mate”, the screen misbehaves. There is a slight “attraction” between the items as they come together. It takes a Reset or powerdown to fix the problem, just removing the TS does not restore the GLCD


Anyone work on this stuff before and have any ideas. I'd sure like to avoid a time consuming troubleshooting session if possible.
