Hi I just connected my Sony TV to the Internet two days ago. YouTube was working fine for the past 5 months . And now it is not working. It keeps giving me the error message 'please check your network connection' everytime I try to get on that app. I checked my Internet connection, I am able to get on Netflix without any problems. I also switched off everything unplugged and replugged the wires, and still unable to get in YouTube app on TV. Even i cannot go the google play store it says sing into google account, eventhough i have given my accounts details and password many times still again and again it says to sign in - use your photne or laptop or use your password. By the way, YouTube works fine on the other laptops and phones.
