EFIS Issue

Everything was going good, I was prepping for my first engine start when I discovered, I had a bad oil pressure sensor. OK, got new sensor. I went to turn on my EFIS (Master) after hundreds of times over the last six months with no issue. No EFIS, No fans on back of EFIS, Check fuse (with ohm meter) good. The control module fan works, lights, radio, all work and starter works. No trim and no Auto pilot. In fact, the master light does not turn GREEN unless I turn on the mags on. What is going on!!!! I did have to send back my Control module to Vans because of a mysterious noise in the headset at low battery power. What is going ON!!! Help, is there a rest on the EFIS?

Jim,
There are two lights on the back of the EFIS, on the ethernet connector.

The yellow one turns on any time the EFIS has power. It's a literal connection from the input power pin to the LED. No software involved. The Green LED should flash slowly as well, but this tells you about software.

So first check- is the yellow light coming on? If not, SkyView has no power.
