I am still experiencing this issue with my new LG Smart TV. The old TV displayed channel info just fine, this one will not. No cable set top box, just coax in from the cable company. Again, same setup i had with older TV just wanted to upgrade to smart tv... doesnt seem that "Smart" now.... I have reset to factory spec, changed the date and time, both manual and automatic. As for timezone there is no manual option only a list of major cities. I chose Denver as i am about an hour away in the same time zone (Mtn) Any help greatly appreciated!
