Question about LG 42LG30 42 in. LCD HDTV

LG 42LG30 TV will not scan in DTV stations

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.

How do I change my service from analog to H D?


Most LCD tv's built in the last 4 years are HD compatible. Most cheaper brands tv's are 720 HD and some are full HD 1080 a little more money. Since their is no more analog broadcast as June 2009 all tv's manufactured around 2006 started incorperating the digital tuner (DTV) along with the analog so that the tv would still receive analog broadcast while the digital transistion was ongoing. All tv's with a Cathode Ray Tube (glass picture tube) are not HD compatible. First you will have 1 or 2 ports on the tv ethier on the side panel or rear panel of the set. They a marked HDMI 1 HDMI 2 or HDMI A HDMI B. If you have these ports your set is Hd Compatible. You may also need to upgrade your cable or satelllite equipment and subscribe to a HD package to be able to get HD service. You will need a HDMI cable to connect your cable or satellite receiver to the HDMI port on you tv. Call your local cable or satellite provider for options to upgrade to HD. Most over the air broadcast stations depending on your area transmit some stations in HD free of charge. A good quality outdoor antenna works best to give you stable signal. You may need to change the settings of the tv as some sets default to the 480i this is the standard digital signal.

Televison station won't scan


If you are receiving a "No Signal" error message, verify that:
  1. All of the cables physically connected to the TV and the input device are secure.
  2. The input device is turned on.
Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:
  1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
  2. If the TV input is not selected, press INPUT until the TV input mode is selected.
  3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
  4. Highlight Tuner Mode and select the correct option:
    • Antenna-over-the air signals from an antenna
    • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
  5. Select Auto Search or Auto Channel Scan. (This varies by model.)
  6. When the search reaches 100% complete, exit to the menu.
  7. Check the available channels:
    • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
    • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.
If this does not resolve the issue, power cycle the TV and then re-run the channel scan:
  1. Turn off the TV.
  2. Unplug the TV from the electrical outlet.
  3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
  4. Release the power button.
  5. Plug the TV back into the electrical outlet.
  6. Turn on the TV.
Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.
  1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
  2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

I am trying to program the RCA ColorTrak Plus TV to my satellite receiver and I get nothing but snow


You will need to get a "regular" Universal remote and program it for that particular model of TV. You will need to access the on screen setup menu for the TV and then have it scan the channels. Make sure your DTV box is on and connected with the coaxial cable. If the "TV Input" button on your DTV remote works and you can get it onto the Video Channel, You can connect your DTV receiver with the RCA Cables (Red, White and Yellow) and get your picture that way. If you access the on screen menu, you will need to scan for Analog and Digital channels as the receiver transmits in Analog. hope this helps.

Why won't my new Vizio DTV work on an antenna without the digital box?


Do you have the antenna aimed correctly and the correct antenna for the distance between your location and the stations? Check antennaweb.org and tvfool.com for the directions to the stations you should be able to receive. Antennaweb assumes an external antenna and is very conservative in the station list. TVfool gives the stations you should get with various different types of antennas. Tall trees and buildings will block signal strength so consider the environment around you.

With digital signals, if you do not have enough signal strength for a given tuner, the channel will not come in. An amplifier may help you get the signal, particularly if the signal is shared to several devices. Failure of an amplifier or lightning surge protection can stop the signal from reaching the TV. A surge through the antenna can damage the tuner.

A damaged cable can also be a source of a problem. Check the outside portion of the wire as well as the interior wires. Replace any that have damaged insulation or ends.

For this TV, if you have done a channel scan with the TV set to the Input TV/DTV, and the Signal Source set to Antenna. Turn the antenna and then set the Additional Scan to On. (Menu > TV > Channels > Additional Scan.) Then do another channel scan.

If you need a copy of the manual, see: http://www.vizio.com/m220va.html#support .
