Unplug the TV set for 5 minutes, so the computer can reset itself and reboot. If it was just locked up, you will have access to your TV's menu. In those situations, I don't even think twice about telling my customers to call the store it was purchased at and talk to the manager of the store, tell them you want to exchange the TV for another one. I tried it already earlier and mentioned it in "Already Tried" section.
To me, that's the right thing to do and the store should be more than happy to exchange a defective new TV for one that works. However I have found on the web the other solution that did the trick.
To check if your device supports 5.1 audio, go to any Netflix Original to see if there is a 5.1 audio option. Many devices will let you customize the appearance of subtitles and captions.
Devices that do not support customization will display subtitles and captions in their default appearance or are not configured to display subtitles.
You could have a defect in the EEprom or the software is corrupt.
Probably something went wrong because after switching it off and back on I get only black screen and nothing is displayed including the menu. If you lost your menu on the TV set, I really doubt that it's related to an incorrect setting in the first time setup.
Sounds more like the TV's computer completely locked up or your display panel lost it's drive voltages that light up the screen.
The down side is that you do have to give them a credit card number, sign a paper stating if it's damaged you pay for the repair, if it's stolen you pay for the TV, but how often does that happen? I think your storm idea suggests that it might be some interference that makes difficult for TV to receive the signal from the remote while in low-power sleeping mode and indeed, while pushing the power button of the remote does nothing except short blink of the red led on TV, holding that button for about 2 second turns the TV on!
Almost like a old car that have a lazy starter so you have to hold the key a bit before the engine starts :)Thanks again for all the information, it helped me a lot and saved me form the headache contacting the local Panasonic service centre.
