If the seller and maker don't support you on this issue, it's grounds for a refund.
But that DATE thing has me thinking you need to get to the setup menu and set the clock and date in the TV. Today's networking systems need the clocks to be within a few minutes of each other.
We just boughtan LG 55" lf61000 smart tv. ..i am unable to access internet-based. Tv and cable work fine. During the set up I was never asked to provide my WiFi login password. The tv recognizes the wireless connection but when I attempt to log in on the login page I get a warning related to a date instructing me to proceed with caution. I ignored it and attempted to proceed to login but the Login is behind the small screen that pops up when I am on the smart menu page. How do I make that little screen go away or how can I get back into the start up menu to put in my password
