It's been 3 weeks since my OrangePi PC stopped showing video from HDMI. I didn't want to touch anything since I'm presenting a project next week and the board is working without any problems through SSH. Everything works but HDMI, and I don't know what happened, just one day stopped showing when I turned it on in the morning and never came again.
Did someone experienced this and know if there's a trick to solve it? I tried different HDMI cables (I always been using HDMI-HDMI) and I even tried it on different TV's but no avail, it is not sending video signal. The port is physically in a good shape, so it should not be that problem I think.

I also installed a clean Armbian 5.10 in other microsd and same, but I could enter through SSH too. It's sad because I wanted to do some graphical tasks once I finished my project but it seems that I will have hard time with it . So pity I just bought it three months ago.

Any suggestions?

Thank you very much for your help.

I'm in the same situation. I think the problem can be design, this board does not have any protection in the HDMI.

This board has no ESD protection on bus HDMI output, and this makes it burns easily.

Yes, missing ESD protection on HDMI is a problem. My friend also destroyed HDMI port on his OPiPlus, although TV out still works.

I see. Isn't any way to fix the part that have burnt? it's nonsense to have the computer like this, and now more since I've finished the project I had and want to do some graphical stuff.

If there is no solution I will buy an Odroid C2 which seems to be way better, I think it would worth the extra money.

hdmi connector goes directly to the H3, if something is damaged it is in the H3

However, you can get a serial console with a 3-pin header and any USB-TTL dongle.

Hello

I have had some problems too with the HDMI outputs.
I'm using an external HDMI switch and after connected it the Orange Pi PC about 2-3 times, the HDMI switch was broken.

It also seems that my HDMI switch doesn't have any ESD protection component.
So if both the switch and the device (Orange Pi PC) don't have any ESD protection...

I don't know if there is a new hardware rev. for this board which include this ESD protection components. If not, it could be nice to do it.
Rem. : My Orange Pi PC rev. board is v1.2

The Orange Pi PC Plus seems having this ESD protection, so I can use it instead without any worry.
The Orange Pi One have it too.

Regards
