.. Have a FLM-373B Polaroid 37" Flat Panel LCD TV. Turned on one day and have what can be described as a "helicopter buzzing" sound coming from both speakers (and anything I plug into the headphone jack). Other than that I have no sound no matter the volume control. I have clear video picture, just no sound other than the buzzing. Depending on the video source selected the volume/freq/repetition of the buzzing changes, only on the HDTV coax cable source does the sound appear to stop, but still no other audio. I already replaced the OEM capacitors as per the post on FixYa.com but still have the same current issue.

pre-amp ic?
Buzzing starts when tv is turned on and continues for 10 minutes and then fades to a low buzz.
