Screen has started to turn green with 4K films

Worth a go. Double check you have the same settings (in guisettings.xml). Then have a look at the kodi log and system journal at the timestamp where you start playing a video.

22

Iā€™ve done a diff on the 2 different guisettings files and the lines with ā€œ|ā€ are the only differences.

(guisettings - Pastebin.com)

Iā€™ve downloaded a 4K demo ā€œSamsung Wonderland Two HDR UHD 4K Demoā€ and that displays OK.

The Samsung video that displays OK doesnā€™t have any Content light level metadata, but both videos play fine on my other Vero 4K.

24

What happens (to Bad Boys) if you set Settings->Player->Videos->HDR processing to ā€˜Force SDRā€™?

25

Still the same.

How easy is it to reinstall OSMC or possibly try the new version?

26

First try resetting Kodi

systemctl stop mediacenter
mv ~/.kodi ~/kodibak
systemctl start mediacenter
27

Still the same.

28

Then restore your .kodi directory,

systemctl stop mediacenter
rm -r ~/.kodi
cp -a ~/kodibak ~/.kodi
systemctl start mediacenter

back up to a removable drive and reinstall.

29

Reinstalled osmc and it is still showing this issue.

30

Not sure if it is related to this issue, but with the USB remote receiver plugged Iā€™m seeing lots of these line in the logs:
usb 1-1: reset low-speed USB device number 3 using xhci-hcd

31

I assume you tried without at first restoring your settings from the backup.

Iā€™m no expert but if your other box is not showing this it does look like a hardware issue. Have you tried swapping the power supplies between the 2 boxes? (clutching at straws, now).

If there is a power issue, itā€™s just conceivable the usb messages are related.

32

This is without restoring any settings, I only configured it enough to get access to my nfs server.
When I changed location of the box, the power supply changed too.

33

Have you tried playing from local storage? (USB or even a short clip from emmc).

34

Copied a 4K film over to USB stick and played that. Has the same green areas.

35

Do you only experience this problem with content that you have encoded yourself?

Iā€™ve downloaded some demos from https://4kmedia.org/ which display OK, but running them through ffprobe -read_intervals ā€œ%+#2ā€ -select_streams v:0 -show_frames -show_entries side_data neither of them have MaxCLL or MaxFALL which mine do.
Also, the other Vero 4K unit I have displays them OK.

37

you could clone the one thatā€™s working to the one thatā€™s not working? If the issue still persists, it could indicate a hardware issue. Also switch psus, to exclude this from being the issue.

38

Iā€™ve got 2 Vero 4Ks, Iā€™ve swapped them around and the one that wasnā€™t working still isnā€™t working and the one that was is still working. This rules out PSUs, HDMI cables etc.

Iā€™ve gone back to a new install and that hasnā€™t helped.

39

I understand that, but if you just wanted to rule out software problems 110%, then you could always clone one into the other.

Then this thread wouldnt be about weird green spots, which everyone assume could be some weirdass software and/or hardware compatibility issue, but actually confirmed hardware failure which then you could rma.

40

Do I need to clone everything or just whatā€™s in .kodi?

This box is at least 5 years old!
