So I just received a Sankyo Star Wars R2D2 pachinko in the mail. UPS had to rebox it as the original box came apart. I plugged it in and turned on the switch but the screen is blank. The R2D2 does cycle and the screen does flash a line or two on start up. I did notice the small plug piece with the diode/resistor that normally plugs in to the card reader port is missing so not sure if that is my issue (I know my super sea story 2 has this). What else should I check before contacting the seller?

Thanks,
Max
