Text edited in red, new findings
E120, new install, standalone, no radar
yet, after 4h on, display went dark in daylight position, all information is here, but to dark to do any work. Changing to night position looks dark violet first, with flashlight it can be seen the PC is working normally. Software update to 5.22 no change.
Examining closely, the E120 is an embedded linux PC.
Changing the brightness has mostly no effect, but after trying in total darkness I oserved, there is faint backlight and when turning the knob (or pressing the joystickkeys), when the indicator bar reaches ~3/4" (18mm) to the right, the backlight of the keyboard goes dimm again to be off in the full right position. Ocassionally, when turnng the knob very fast left/right, the backlight of the disply comes back for a second, but only partial as there would be a flashlight on the right side below the monitor.
Boat is new, not in water yet, 13.4V as permanently the battery charger
is on (designed for that) to float our 400Ah Gel-bank, 28°C all time, back of E120 is free to air in aircond room, can not overheat.
Someone had similar problems and any idea for a "field repair
"? Any idea would be highly appreciated as I am in the Philippines and Raymarine
service is far far away and not cheap anyway. Note, this is steady, not similar to the backlight on/off at night.
