Question about LG 42LG30 42 in. LCD HDTV
I tried a usb cable in the back of my 42lg30 but it didnt regester and the owners manuel said its a service port what does that mean and how can i use it would like to connect my laptop to tv
By service port they mean a device hookup that a tech can use to diagnose problems with your TV. There is no practical use for you to plug into it. If you want to display your laptop on the TV you need yo hookup the video out from your laptop to the TV's PC/RGB input.
Hope this helps FixYa,
