The Marine Power Display (MPD) requires operating software. This software is flashed directly into the MPD through a J1939 datalink. When 213-1907 flash files or 217-8181 flash files are flashed to the MPD, the MPD screen may turn light gray (losing all the gauges) or the MPD screen may turn black. When the MPD turns gray or black, the MPD has not failed. There has merely been a drastic change in the contrast of the MPD screen. This problem may also occur while the MPD is in night mode.
