I'm very sorry to hear that has happened, and I apologize for any inconvenience this may have caused you. In order for me to help you most accurately, please provide the complete model code for the TV?
I bought a new 55 inch Samsung Smart TV with a included keyboard. When I am browsing the internet, the Tab Key does not move to the next field like it does on a computer. It is very difficult to move from field to field on a form without this. How can I get this to work correctly?
