Tv purchased from a hotel and its locked i can only use hdmi on tv if i connnect an antena it wont show local channels , when i change the channels it shows the number from the hotels cable provider , i also did not get a remote control with this i tried using an universal control remote but it wont let me access the "secret menu" to disable the hotel feature after reading online , does any one know a way arround it or knows maybe of an antena that will work via hdmi instead of coax
