Question about Panasonic Home Theater System System
Usually problems that start "out of the blue" after being powered-up for hours, caused by heat building up are due to things inside getting hotter and hotter until they fail. Unless something actually burns up, this is a reversible problem. Shut it down to allow it to cool off, and it works again. I own a SA-HT700. After 24 hours or so of being powered-on. it starts making a loud rumbling noise. Turning it off for 20 minutes fixes the problem. There's a fan on the back of the unit. It does not work. The heat sinks inside my unit are not covered with dust - suggesting the fan has never worked. I rigged an external DC supply to the 12V fan, so now the fan runs all the time. I am waiting to see if this fixes the problem.
