When I press the edge light control button on 2019 Newport, the lights over the island blink momentarily. On the main control panel the green light flashes for about 4 seconds. We have been stationary for 2 weeks and no issues until now. All other lights work. Looking for the location of the KIB control board for possible troubleshooting. Manual for KIB advises it could be a wiring or grounding issue. Thanks for any advice since unit is out of warranty.
