same vibration on my 58" panasonic plasma from sub-woofer
Hello,
Found your post and really appreciate all the detailed information you provided. Pretty much summed up my guess as to the issue around the sub-woofer against the back panel and not enough or too much padding against the panel.
Can you send me the name/contact information you have on the Panasonic Field rep? I actually have a 2 year warranty through Costco (basically an extention of the 1 year panny warranty), but wanted to have the contact information in case I need to go that route.
Thanks in advance
