New smart TV and im stupid help !

[m.j]

So I purchased the Sony 55w905a and love it , but when my ps4 is on, the option button for changing picture settings doesn't work , when I go to any other device I can do it. Blu-ray and ps4 go through hdmi to amp and amp to TV , have turned off hdmi control on ps4 , just can't figure it out and it's bugging me.

Any ideas?

All sorted had to turn off bravia sync in settings.
