This Japanese slot machine made its way to our repair shop this month. It came to us giving an error code on the screen and refused to play. Upon opening it we found some bent pins on the cable connectors and some cold solder on the mainboards. We dismantled eveverything, cleaned the rollers, resoldered the boards and it still gave us an error. Then we discovered that the machine needed a full hard reset. After the reset it was playing like a champ!
