Having an issue with my lower right JP flipper. Undertook a flipper rebuild due to weak right lower flipper. Rebuild went without issues, resoldered all wires as they were initially based on pre-disassembly pics. Powered up the game and it played great for two games. Right flipper had power and was playing great. Then right flipper suddenly stops working. No flip at all. Remove glass and I can feel a vibration on the flipper itself when the button is pressed. If you move the flipper to the top position and hold the button it will stay there. Flipper seems to move freely without binding. Further diagnostics so far show that the LED light on the flipper board does not light when I close the switch at the button. Other flippers light normally including the upper right flipper which is on the same cabinet switch as the lower right one. All fuses on the flipper board were metered out and are ok. Rechecked all wire connection and solder joints and they seem ok.
