Question about LG 42LG30 42 in. LCD HDTV
I purchased this TV in June 2008. I do not have satellite or cable. Of the 4 stations I receive, all but ABC have been digital for weeks if not months and I have had excellent reception. When I channel scanned on 2.18 to bring in ABC, I lost the other three stations and on 2.19, after the TV had been unplugged all night, I scanned again and now have no DTV. I get NBC analog, but none of the digital stations. It seems this must be a TV problem in the scanner function since the TV works and the DVD works. I have read the manual (no help) and reset to factory. I do not have another digital TV so cannot use comparison to trouble-shoot. Any help appreciated.
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.
