We installed one this morning (Hookedonslabs unit). Everything seemed to work for about 5 minutes. When checking out settings, I opened the "wrench tab", the unit locked up. It displayed wide and narrow vertical lines.

Had to remove power from unit to restart. Now, on startup, after "loading", the first select pages appears. Whatever you select here (simulator, normal, etc) the unit immediately locks up. Vertical lines.

Any clues?
