Got this batman data east that plays good and everything works except the display. On first glance I see really burnt connectors on the power supply board. Looks like the traces on the board are blackened and not green anymore too. Also looks like one of the fuses may be burned. I tried swapping the direction on the display ribbon cable and reconnecting the connectors on the display and Power board, but no luck. I have seen the display flash a glimmer of life, lighting a few pixels after I turned it on once, but never happened again. I've never done much repair besides soldering a loose wire and changing lights/rubbers. Never changed a fuse or measured voltages. Should I start with just buying a new power supply board or is there something simpler to check first? Thanks.
(also the thing circled in red flashes a blue spark when I turn the game off). not sure what that is or if related.
