Question about Sony STR-DG520 Receiver
Recently I bought a STRDG520 AV receiver. I am facing a noise problem when I use the system with 5 speakers enabled. Initially when I switch on the system and will get a very good effect from all the speakers but after 3 to 4 minutes I can hear the noise from the speakers which gradually increases and makes the sound very distorting and will be not able to hear any conversation / background music and will be only noise. Plz advice me what would have happend.
Its may be because of over heating of main Audio Amp IC please check it and apply thermal compound between IC and Heat sink if required.
