Hey all, I just installed a Sophia 2 in my 800XL. When I type sometimes the screen quickly blinks and comes right back like it's a short or something. The RF shield is off so nothing is pressing down on the Sophia itself. In experimenting I just noticed that if I move the path of the ribbon it seems to go away. When I had it running to the right and then up to the hole out the back it had the glitch. However, when I run it up to the top first and then right and out avoiding the middle of the board, it seems to no longer happen. is this a coincidence or is there something possibly shorten on the board that I need to be concerned about? Here are photo's of the two paths. First is the path across the middle that had the glitch and the one on the right is the one that does not.
