Summary: Bought the Panasonic because it was priced less than a comparable Sony. Replacement television will be Sony.
Pros: Nice picture/adequate sound for the 16 months I've owned the TV. The television was used fairly lightly; it's located in the master bedroom...the big Sony in the media room carries the bulk of the family's television watching.
Cons: Lasted 16 months. Pop...10 flashes on the Power LED...no television. Lots of bad experiences with Panasonic Viera televisions are chronicled on the net.
