anyone has any idea how this can be fixed?

below is the /boot/config.txt

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan

# goes off screen, and negative if there is too much border
#overscan_left=16

@shingouki What is the resolution of your TV?
Did you create an edid.dat file for some reason? Was the Pi not seeing the television?
Why have you got this set to 1080p @ 50Hz? Most TVs would be hdmi_mode=16 ie 1080p @ 60Hz.

Have a read through this regarding EDID and hdmi_mode https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

i think this sort of picture can happen if you have a bad HDMI cable. have you any others you can test with?

Looks like this is the cause, changed the cable and now it is fine. Thanks for yout help..
