Blank Screen on EFIS2, No engine or fuel data on EFIS1
We have dual Advance Deck 5600s. The left screen boots up, but missing data, see picture. Right screen blank, but the fan is working, so it's getting power. I had hoped it was a loose connection somewhere, but so far that search isn't fruitful. My co-owner thinks we will probably need to send #2 in for repair, but I'm still optimistic we can find the problem. Any help so he's not right, again? Thanks.
One more bit of info that might help. Pressing the lower left button on the blank (Efis 2 on the right) does not start it on battery power as it should.
The fan power is probably coming from the SV-Network connection into the 15-pin connector provided by the working screen. Try booting on backup power by pressing and holding button one for 5 seconds. There are two lights on the ethernet connection that can tell us of the unit itself is getting power.
