Ok.. Something has happened.. and I dont know what.
The device in question is a D-100, new, barely installed. We ran the internal battery down prior to installation demo'ing it during hangar flying. The device has been stored in a hangar environment. We installed it into our panel Saturday morning and connected ONLY the power 14v + and Ground leads. The remaining wires on the premade harness from SteinAir were left unconnected.
When ships power was applied Saturday, the Dynon powered up and all the screens were accessible. Displays seen were consistent with a stationary aircraft with no EDC connected. Ships power was cycled numerous times which caused a cycling between ships power and internal battery, but the device was left powered externally for at least 3 hours straight, and 5 hours cumulative time (static display at an airshow). Internal battery time during this period was estimated as less than 3 minutes.
Device was located inside an aircraft, inside a hangar with an open door. Rainfall did occur, but no direct moisture entered the cockpit. When not raining, the aircraft was outside of the hangar on the ramp. Ambient temp was short sleeve weather and humid. No condensation was observed on any components inside or outside the aircraft or cockpit. Coldest temp since installation was perhaps 60 degrees F, hottest temp 90 degrees F estimated.
Today, sunday morning, I went out to the ship and tried to power up the dynon for display, got a flicker only, followed by a black screen. The screen is totally black. I ensured power and ground continuity to the pins on the premade harness. I ensured no other wires were connected (no other hots were possible, and minimal grounding opportunities were present). When I attempt a power down, 2 seconds hold on left button, followed later by a short press, I get the flicker (less than a second of a screen starting to display) followed by black screen. I still have the protective plastic on the screen but thought it is clear and not contributing to dimming the screen, and have not removed it. With the exception of the flicker, it is not possible to visually distinguish the black screen from a power down condition.
I was starting to think perhaps someone had over-dimmed the display when the cockpit was unsupervised, but the online manual indicates that this should not be possible.
Is there a master restore function of any kind on the box?
Are there any pointers for field troubleshooting this problem?
