Panasonic SC-HT900 Audio problems

My panasonic system SC HT900 with a powered W350 subwoofer will work( Put out sound) for about five minutes after i turn it on then the audio will quit, all displays and functions on the front panel will work. I am an electronics tech by trade and i have looked at the power amplifier module located in the subwoofer. The unit uses a RSN311W64 6 ch audio ic. I dont have a data sheet on the ic or the system. i have also noticed that during the five minutes it works the fan will come on for a few seconds every thirty seconds. The only way to get the audio to come back on is to unplug the power cord for about an hour and then plug the cord back in and turn the unit on. yesterday the audio will not turn on any more

    system produces sound for a few seconds & then goes out; panel functions appear normal. How quiet is the subwoofer fan? Perhaps the fan no longer works.

Hi I have a panasonic theatre surround system model number SA-HT900 but I need a remote for the unit but can't find one anywhere . There is another model a panasonic SC-HT900 will the remote for this...

The remote for the SC-HT900 will work with the SA-HT900. The SA-HT900 refers to the model number of the amplifier of the home theater system but the model number for the whole home theater system including the speakers is SC-HT900.
