@sam_nazarko Thx for all the effort you put into this! You try to help with every problem. With so many users, well done!
I have the same blue/green screen problem with my Sony Bravia LCD TV 50 hz (2009). In this thread they only speak of Philips TV’s. I’ve tried to edit the rc.local file throug SSH but always permission denied (in root + sudo). I tried to change permissions with ‘sudo chmod’ but denied as well.
A few days ago I updated my vero 4k. The option ‘force rgb output’ was added. I turned it on and did reboot. Now the problem happens less often but it’s still there.
I know it’s time for a new tv but that will be for later. Is there anything else you can do?
Thx in advance!
