I have just bought a second hand Sony Surround sound system.
I have noticed when the system is off there is a small humming/buzzing noise that comes from the unit. But when I turn it on the buzzing stops.
Would anyone know what this noise could be?
It is a system that was bought from Dubai originally, so could it be that the power supply is different.
I can live with the noise as it is very quiet, but I just don't want to leave it if it could be something dangerous.
