HDMI Daughter board does not produce video

Hello and thank you for the Eon NAS case. It’s a nice piece of work!!

The HDMI Daughter board does not seem to be producing any video. I’ve tested the RPi V4 alone and it works fine. But, I get no video when I plug in the daughter board.

I’ve tested the daughter board with a 2nd RPi V4 and still does not produce any video.

Any troubleshooting advice?

Thank you very much!! I’m a big fan of the M.2 cases as well.

Thanks…dP

@depluma can you try to make sure if the hdmi board is plug in properly, there might need a little force to push the daughter board in. Also try to check if there is no output detected in both HDMI output. If this still don’t work, can contact our support at cs@argon40.com, we will arrange a replacement HDMI daughter board after the CNY break.

Agreed…I’ve tried to push it in farther…but, there’s a part of the board by the Audio jack that hits the RPi USB riser…and prevents any further “pushing”. I’ve debated about filing down the portion of the board to see if it will go in farther…but, that may interfere with the alignment on the holes in the back of the case.

I’m thinking a replacement is in order. But, I’m fine trying the filing down thing if y’all would want me to try.

I’m available to try what’s needed…thx…dP

@depluma there is no need to file parts for fitting, as long as most ports are push in. Would also request to try both hdmi port, we have encounter issues on loose solder on the micro hdmi header causing the video not showing, but it is very rare that it would occur on both output.

I’ve tried both ports and neither produce video. Thanks…dP

Yes, I have exactly the same problem here… I have an Argon One M.2 that works fine…
neither of the HDMI ports give a signal I have tried the cs@argon40.com email but they seem …
well slow to reply…

depluma, did you find a fix for your system?
