I'm running Mate (LTS) on my new RPi3. Everything is working fine as long as I plug in an Ethernet cable. If the cable is removed, my screen (connected via HDMI without adapters) immediately turns black. As soon as I again plug in the cable, it turns back on.

Any ideas?

// an empty Ethernet-cable does not give me the screen, only a cable with a connection helps (But a wifi connection has no influence)

    Sounds pretty weird. Does the screen work if you unplug the ethernet cable before booting the Pi? – goobering Jan 17 '17 at 17:25

    no. I wrote the image to the SD and was quite frustrated by the black screen (thought I made a mistake while writing the img) and only got an output when adding the Ethernet. – FooBar Jan 17 '17 at 17:27
  • Anything in any way unusual about the other end of the ethernet cable? No PoE or anything? – goobering Jan 17 '17 at 17:28

  • If you feel like investigating this, I suggest plugging in a loopback cable (with pin 1 connected to pin 3 and pin 2 connected to pin 6). Otherwise, I would just try to return the board to the seller as defective. – Dmitry Grigoryev Jan 17 '17 at 18:02
