SOURCE: Scanning dtv channels
go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.

Sounds like you're having a problem with your main board assembly. The main board is what processes all your audio/video signals. So if it's not scanning DTV you've probably got a bad card. Call LG's customer support line at 1-800-243-0000 and have them schedule you a service call. Request a DMST if there's one available in your area as they actually work for the factory. Otherwise you may get an ASC(authorized service center) which can be less than reliable at times when it comes to customer support and satisfaction.
Remember to have your proof of purchase handy as well as the full model and serial number. And by model number, I don't just mean 42LG30. On the side or back of the unit there will be a manufacturer's code. The first part is indeed the model#. However, it will appear something along these lines:
42LG30-UA.AUSRMJR or something similar to that.
Have that ready definately. Any tech worth their salt will call you a few days beforehand to try to get that data so they can order boards before coming out there, saving them, and you, an extra trip when they have to come and order boards. Without that extended manufacturer's code, LG techs have a hard time with a lot of models trying to order parts as different revision codes and such use slightly different circuit boards.

You need to go to your menu option with your remote. Select channel scan from the options listed in setup. This will allow the turner to find your DTV channels again. Hope this helps. J
SOURCE: wont tune in dtv
Does it have a digital tuner? If not, you need a set-top box. If that's covered, you may need an antenna.
SOURCE: Problem, unable to access any digital channels. TV
If the database is empty you need to re load the system.
With your remote controller, go to menu and from that you need to select install or setup.
This will scan for all available channels and store them for use.
Hope that helps.
