When I go to this page:
to register my new Q6FN I cannot enter the serial number into the left-hand entry box. With Firefox, typing numbers/letters makes no appearance whatsoever, with Internet Explorer 11 the depressed key appears in the first character slot (very) momentarily, but again I can't enter my S/N.
How to register my new product??? I am logged-in to my account when I try this, and I can see my other TV (a Frame) among my products. Just can't enter the new one!?
It turns-out that while the Registration page does not seem to work at all when accessing from a Windows PC, I was able instead to use my Apple iPad and Safari browser to register my new TV.
