Broken GUI and freeze during boot when HDMI is connected

Hi everyone :slight_smile:

I recently bought a new TV LG OLED48C17LB and while I moved my Vero4K from my old TV to the new one I realized that it was not booting (or might be freezing during boot, Vero4K is not reachable via SSH). So, wanting to make a fresh install anyway, I installed the most recent image, but the problem remains.

Interestingly, when I boot Vero4K without HDMI connected everything works smoothly until I plug in the HDMI cable. Though the device does not freeze and is controllable, the GUI seems to be broken:

I don’t know if logs are persistent across reboots, but I provided them anyway:

If you need more information about the TV or something else or if you want me to change any settings, please tell me.

Thanks a lot and kind regards,

This doesn’t look good. It looks like we can’t identify the TV’s EDID.

Is the HDMI cable connected directly to the LG TV?
If so – can you try a different port on the TV to rule out an issue with that port.

If that doesn’t help, can you try another HDMI cable?

Hi Sam,
thanks for your incredibly quick reply.

Unfortunately I already tried 2 other cables and all available ports with the same issue. And yes, it’s connected directly.


I’d suggest cleaning the device’s HDMI port with contact cleaner then.

Ok, I’ll try that, at least I know now what to watch out in the log files…

Short update: When I restart Kodi via SSH from the screen shown above everything works normally. I will also use an old Raspberry later this week to further rule out any issues…

I’ll keep you posted.
