Yes – it looks like your TV advertises support for a colourspace it doesn’t support. It also appears to be a 2009 era Philips TV, which is what we expected:
Rx Brand Name: PHL
Rx Product Name: Philips
Manufacture Week: 8
Manufacture Year: 2009
We had a fix for this in an older version of OSMC, but it required manually setting the colour space, as the Philips TV is sending an incorrect EDID.
It hasn’t been tested in a while however.
echo 'rgb,8bit' | sudo tee /sys/class/amhdmitx/amhdmitx0/attr resolve the problem?
I can try and produce something that handles this TV quirk in a more automatic manner if you’d be willing to test it.
