Yes, this issue has been troubling--and incredibly frustrating, given that I've been without a working TV for 6 weeks on a unit that was 7 weeks old when this issue first occured. I tried everything I could, but they would not replace or refund the TV, even after the first repair didn't work. In my case, they did replace the entire module, but it didn't take. After having the unit on for 2-3 hours, it shut off again repeatedly. They said that sending the unit to the factory was the most expeditious and best way to resolve the issue, rather than keep sending people to my house. I was told by the tech that the entire process from pickup to return would take 5 days. Well, it's 2 1/2 weeks since they picked the unit up (3 1/2 weeks since they said it would have to be sent to the factory)...and the TV is scheduled for delivery to the local service center today. Hopefully they'll deliver it tonight, but when I called to give the tech a heads up that the unit was on its way he responded by hanging up on me. I'm crossing my fingers this fix took, otherwise I'll have to prepare for more (and I've already had my fair share of) headaches dealing with Panasonic.
