Is your LG TV s smart TV? If so, you will need to get an app onto your phone called allshare/smart share from Google play (if its android). Then you will need to have you TV and phone on the same network. If you go to LG smart share, it should recognize your phone and work similarly to bluetooth. If your screen is broken to the point you cant install the app, upload the files from your phone onto a USB and transfer them to your TV manually.
Looking for info on downloading pictures from phone (with broken screen) to a PC laptop. Any tips would be greatly appreciated.
