Never thought that showing a website on a tv would be such a challenge
We have the WIFI adapter to connect to the network and www

After showing a random website (for example thru Net TV, after 10 minutes the screen goes blank and goes back to the "no video signal" screen

Is this normal behavior or can I set some preferences that I did not see?
I have tried a couple of options and with and without updating the tv (doesnt matter)

Thanks on forehand for explaing or guidance
