Mu8000 and PS4pro - resolution problems

[AdamT1]

Hello

My TV (ue65mu8002)-console(ps4pro) have developed a problem, it shows that there is no source (till 2 days ago everything worked fine 4k and hdr)

First of all i have bought a new top of the line HDMI cable - from hama rated for 4k and hdr, and tryied to plug it to all of the 4 hdmi ports

When HDMI UHD color option is switched on for the hdmi ports then, only 1080p resolution is working (720 and yuv are flickering) when switich to automatic it shows no source

when HDMI UHD option is switched off, then automatic resolution is active, 4k is active (only yuv, rgb is not active)but the video is flickering with a black screen in every few secconds

Im becoming so frustrated... firmware is updated for the tv and console
