Recently I've received a RPi 3 - model B on which I installed Raspbian. After configuring the OS and adding some stuff I've shut down the Pi. Next day I took it with me to school, from there on all screens I've tried (4 types) said no HDMI input found.

I've used:

  • hdmi_force_hotplug=1
  • hdmi_drive=2
  • config_hdmi_boost=6 (and 4)
  • hdmi_safe=1

I can confirm the SD is ok, inserted it into another Pi 3 at school, worked great. Also the ethernet port 'works' (both leds work)

Does anybody have a suggetstion? Please?

    Have you tried using different HDMI leads? Does the HDMI port look on the Pi look normal? Did the Pi work correctly before being taken to school?

  • I've tried 4 HDMI cables, of which I've used one before. HDMI port looks OK. Pi worked as expected

  • I guess it got damaged on its trip to school.

  • Could it...? I've protected it by putting the Pi in its original box and I didn't throw my bag around or anything like that :/ Also the pi is in a casing

1 Answer 1


After a quick call to the company that sold them they asked me to send it back. It's probably a real HDMI defect...

Thank you for your support!

    Best guess is something in the HDMI connector broke when you plugged it in or pulled it out. Sometimes the defects don't appear until they're strained once or twice.
