Our controller had a nasty accident. The display backlight supply touched chassis and burned out a 74hct245 data buffer then sent high voltage down the ribbon cable to the controller board and burned out seval chips. I can replace all the chips but the eprom with the software is toast. If anyone could make an image it could really save my bacon. I used a very simple arduino project to read it. Three data lines stuck.
