My first post, so please be gentle. I have a Klegg M6 501P11 home cinema system, which works and sounds great when connected to my digital output of my DVD via Optical lead. However, if I change the lead to Coaxial I get a constant hum from the system. I do have the TV connected via scart for sound from my cable box, to watch TV without the home theatre system. Any ideas?
I have this same problem, But mine is caused by using the incorrect cord, I dont notice the hum ever if anything is going though. Possibly change the location of the coaxial cord to a diffrent input and see if that will change anything.
