Hi! I have a Philips MCM530/37 system with speakers to match. Recently I’ve been having an issue where when I plug it in, the red power light comes on for a second and I hear clicking, but then it shuts off and I can hear a low, very quiet rumbling noise. That repeats for as long as it’s plugged in. I’ve tried unplugging, replugging, even a different power cord, but it just won’t work. I read a thread about a similar issue where someone said something was shorting. Has anyone had this problem? Is there anything I can do or does it need to be professionally repaired? Thanks in advance!
