Victron Display randomly flickers dark for half a second – any idea why?

Hi everyone,

I’m experiencing an issue with my Victron system where the screen randomly goes dark for about half a second and then comes back. This has been happening for quite a long time now.

From what I can tell, there are no voltage drops on the battery and all the wiring connections are solid. I’m not 100% sure, but it seems that the flickering doesn’t happen when I’m connected to shore (ground) power.

I’ve recorded a short video showing the issue. Any idea what might be causing this?
Thanks in advance for your help!

Did you extend the USB and HDMI cable?

No

I did another test today and found out that this issue only occurs when the brightness is set to 100%. For instance, if I set it to 75%, the flickering completely stops. Therefore, it’s likely a software bug.

Regards

Interesting as it does not explain the shore power observation. Which USB port is used to power the screen and do you have other USB devices?

Do not think it is a software bug, it sounds like a power consumption issue, max screen brightness increases power draw and something has a problem. Voltage higher on shorepower avoids this. If it was a software bug there would be more reports of this.
