Hi, On my new Philips 32 inch 8807 TV occasionally when there is a very deep bass in a movie soundtrack (only noticed via DVD so far) there is a sort of a buzz or vibration that does'nt sound quite right from the speakers. The set has Virtual Dolby Surround sound. Just wondering if this is a problem with my set or if its a common problem that could be solved later by going for an external sound system and muting the sound on the TV. It only happens about twice throughout the Road to Perdition and about four times in Manhunter. Seems to be whenever the soundtrack plays at certain frequencies or whatever. Or is this part of the effect intended by the manufacturer (some chance!). Dissapointing however, as the TV cost 6 or 7 times more than my Micro Hi-Fi system (Sony entry level) that has great sound from CD. Any advice greatly appreciated.
