I have a Raspberry Pi 3 Model B and I'm trying to output video from the pads on the back of the PCB, how ever it is not outputting video. I've tested the video with a raspberry pi zero and the video outputted fine. Its just not working with my Pi 3 Model B. When typing:

tvservice -s

It outputs:

state 0x40001 [NTSC 4:3], 720x480 @ 60.00Hz, interlaced

The config.txt does not have:

hdmi_force_hotplug=1

So it is commented out and not being read, another attempt trying to get it to work I added:

hdmi_ignore_hotplug=1

to the config.txt also. I need to have the video SOLDERED to the Raspberry Pi! Please help, I've tried everything and nothing is working.

EDIT: The composite display is connected to PP24 on the back of the Pi

  • to rule out the obvious is anything connected or plgged into the HDMI? – Steve Robillard Apr 6 '18 at 21:54

    The Pi3 is not designed to have video soldered - who knows what you connected where? – Milliways Apr 6 '18 at 23:36
  • There is nothing in the HDMI plug... And the Pi3 must of had intentions of people soldering video to it, why would PP24 be there? I have my screen connected to PP24. – SeanOMik Apr 7 '18 at 2:28
  • Sorry for a stupid question, but did you connect ground? – Dmitry Grigoryev Apr 10 '18 at 13:00
  • Yes, I did, its connected to PP06 – SeanOMik Apr 10 '18 at 21:04
