This speeds things along.
The TV is clicking on and off. Will not stay on for more than 3 minutes and after a few minutes of clicking it turns itself back on! Saw that MANY people were having the same problem so I called the 800 number and was told by Lynn that they only come out to do a fix on the LCD. "DONE DEAL" is what she advised me. Your plasmas are having the same PROBLEMS as the LCD. Mine was manufactured in 2007. Please help. I am not satisfied with the response from the customer service rep.
