Hi All

I have my Dads old Beovision 7 type 9443 with 7.2 soundbar for my man cave which is running my xbox s really good

The issue i have come across is there is a loud humming coming from the TV not the speaker when i switch it on and stays there. When im playing a game or watching a film i can ignor it but its still there.. ?

After some investigation i have noticed when i put the contrast up to full the sound (humming ) goes away ?

any idea how i can correct this so not to have the contrast at full
