Yes, I am an idiot. I was doing a cap replacement on my TG16 and wanted to test everything before re-assembling the unit and I accidentally plugged my Super SD in shifted by one column of pins to the left or right, not sure which. The Super SD boots and more or less works as normal _except_ now its constantly scrolling the image. I tried updating the firmware to the latest since this is about the only thing I can try - needless to say it did not work. I also inspected the board for any burnt components but everything looks and smells as it should. I'm hoping the Terraonion team might be able to suggest some options.
One last thought, I tried the Super SD on another TG16 to rule out my cap replacement job but I get the same results.
