Hi, Phill77 posted a message on 12/11/03 regarding the humming/buzzing on a Panasonic TX-28DT4. I bought the 32" version last week and have noticed the same thing. When the sound is low and there is lots of white/light colour on the screen there is a noticable buzzing. Has anyone else noticed this? I'm really happy with the TV except for this. I've emailed Panasonic but I'm still waiting for a response. Thanks, Dave.
