I took the TV out of the box, plugged it in and nothing. After pushing the on/off switch repeatedly, it finally came on. Picture and sound were terrific so I was very pleased. Turned it off with the remote. Of course, the TV wouldn't turn on again with either the remote or the switch. Pushed the switch about 10 times and it finally came on. I called Panasonic customer service who could not do anything to fix it by phone. So now my new TV is in for a warranty repair less than 24 hours after I received it. Talk about frustrating!!!
