SOURCE: LG 42LG30 TV will not scan in DTV stations

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.

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike

SOURCE: My LCD won't tune into DTV

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

The DTV input in my GV46L stays black. Why?


You don't say what you are trying to input but take note that your model does not have a digital tuner on the DTV input. If you use a digital OTA antenna, the signal must first go through a digital converter or tuner before it goes into the DTV input. The DTV/ANT input is only cable ready. There is no digital tuner in the TV to activate the DTV menu.

Black box comes up on tv screen


The black box is a text box for closed captioning. Some stations send the signal which turns on the box while not actually broadcasting any text. Go into your setup menu and turn off closed captioning, or at least change it to a different mode. The easiest option is to restore factory presets.
