My friend subscribed to this recently. It has no sound despite my checking audio and rebooting. Now he wants to screen cast to his Panasonic plasma tv. It's a TH-42PZ85U. I have no idea how old it is. When I tried screencast it showed a bunch of tvs to send to, but I'm pretty sure his is not on the list. Also, I went to a website with my phone, the Pure, only to find I had no Internet connection. I don't know why because it's the same thing I've been using for quite a while. It says the signal strength is excellent but it doesn't connect.
