Top 1/3 of MFD is dim, bottom is somewhat dim

Post by kjmeyers1 »

I'm wondering if anyone has encountered what I have going on with my MFD. On my last flight I turned on the G1000 and the PFD was normal, but the MFD was pretty dark/dim on the top 1/3 of the screen. The bottom 2/3rds was not nearly as dim, but not the normal brightness. I checked my screen settings. Both screens are 100% and on Auto. I took the MFD off of auto and set it for manual. I dimmed it all the way down and back up. No change. I got to my destination and some hours later left and it was the same situation on the way back.

Any ideas?

Also, if it happens that I need the MFD panel itself replaced/repaired, does anyone know how much a replacement costs?

GDU1040: flat rate $1400.

The other MFD versions (with garmin autopilot) are 1500 / 1600, depending. I don't recall the model number there.

Hi Jeff,

It was a temp issue. My hangar was 55 degrees or so and when I got to my destination it was 70 degrees or so and I left the plane for a few hours and when I got back it was warm inside and it remained the same.

Ken-

Did it turn out to be a failed GDU?

Hi Tim,

It was the GDU that went on the fritz. My Diamond Service Center got the new screen last week and it should be installed this week.
