Make sure you are scanning the right modulation (there is AIR for antenna and CABLE for cable). If this still does not solve it, you need to replace the tuner. It depends on the make and model but most of them are located on the main board. Sometimes they have their own board that will save you some money as you do no need to replace down to component level and just swap the board.

Why won't hd channels be found when I tune my 42


It depends where you are. Digital has replaced analog signals. If you don't receive channels, ask a friend or neighbours on the situation with their TV. If their hd TV are working properly, then you may have not tuned the TV properly. Have you chacked the Antenna cable? Yes? Then tune it with care and watch what happens. Normally, the TV will show if a signal has been detected. If you have no signal, you need a technician because there are more than one reason this is happening, probably you haven't connected the Antenna cable. Who knows. Again, check the antenna cable, is it lose or wrongly inserted? If you have a small digital TV, connect the antenna to that TV and see if the channels are working. If not, it's probably the cable from the wall socket to the TV (change the cable) or the Antenna cable had been a meal for a rodent on the roof. As I said, who knows?

Emerson hdtv does not pick up any antenna signal


With digital OTA TV signals, a lot of things could cause you to fail to pick up a signal on any channel. First, do you have an indoor or outdoor antenna and how far are you from the transmitters for you local stations? Digital signals are either enough to for the tuner to interpret or you get no signal. Next check that the antenna is pointing at your stations' transmitters. Use antennaweb.org or tvfool.com to check the direction for your location. Antennaweb assumes an external antenna and provides a very conservative list of stations.

Check for buildings, hills or tall trees that might block the signal to your location.

If your antenna is providing a signal to several TVs, try a direct connection (taking out the splitter). You may need an amplified splitter to minimize the signal loss. Note: amplifiers (whether at the splitter or part of the antenna) can fail and become signal filters (blockers) instead. The direct connection tests this as well.

If another TV does pick up the signal from the antenna (at this point), then the tuner may have failed. It may also just be a weaker tuner compared to the other TV. Surges (for example, lightning strikes) can cause a tuner failure. In that case, you need a new tuner. (a stand-alone tuner like the converter boxes might work) or try a site like shopjimmy.com, searspartsdirect.com or partstore.com. SearsPartsDirect lists the tuner here: http://www.searspartsdirect.com/partsdirect/part-number/Emerson-Parts/Television-Parts/UTUNATSSP006/0057/528/Model-LC320EM9/0352/0333600?keySuffixId=NA&pathTaken=partSearch&pathRender=modelComponent&documentCompId=50034435&diagramPageId=00001&productTypeId=x&searchModelNumber=LC320EM9&subCompDesc=Lcd%20tv&brandDesc=EMERSON&modelDesc=LCD-TELEVISION&blt=11&shdMod= .

This TV was made by Funai so you may see other TVs that use the same part.

I hope this helps.

(I have two TVs with different quality tuners. With one, when the antenna shifts slightly out of place, I can lose the ability to tune in the channels from the closest transmitters. The other TV does not lose the signal until the antenna rotates more than 90 degrees from its usual position.)

My box is hooked up but it's saying no signal...I read a post from another person with the same problem and what the "Expert" said. I had already done the scan thing but it's still telling me no...


What type of antenna installation are you using? Do you have it aimed at your local transmitters? Do you have tall trees or buildings that could block the signal? Do you get signal from a low-power analog station in your area (pass-through or direct)? If you have an analog station with a transmitter near that of the digital ones, you'll have some idea of if the antenna is pointed correctly. (Digital signals do not get tuned in the way a weak analog signal does. There is no poor picture option; you either see it or you don't).

Go to antennaweb.org or tvfool.com for information on station transmitter locations that you should be able to receive (if in the US). Just enter your address. Antennaweb is very conservative in the channel list even though it assumes an external antenna. Tvfool gives recommended antenna types for each transmitter in your area. The antennas are labeled with a color code by the manufacturer.

If you are sharing the OTA signal from your antenna with several TVs, you may need an amplifier.

I've had one D-T-A box fail due to a lightning strike hitting the antenna; the tuner was damaged by the power surge. I've also had amplifiers that lost the VHF (2-13) channels after a surge. If you have a lightning protection system, check it as well. The simplest diagnostic for these problems is checking if a new D-T-A box or a TV with a digital tuner can scan the channels and then check what the signal strength is for those channels.

Some tuners are more sensitive and will receive a channel that another tuner might not see as a strong enough signal. An amplifier can be useful in this case as well. (With the amplifier that got hit by lightning, one TV was still receivng channel 7 but the signal strength was 1 out of 7. The other TV got no signal due to a weaker tuner. Since that channel was from the closest transmitter, the amplifier was checked once the antenna direction was confirmed to be unchanged.)

I hope this helps.

(Antenna type, tall trees and direction are big issues. I set up a neighbor's DTA with an indoor antenna that got one set of stations. Due to placement issues, their other TV got a different pair of stations with another indoor antenna.)

I got an American model of LG. i can not tune it by auto nor manual can you please help


You can get a manual here: http://www.lg.com/us/tv-audio-video/televisions/LG-lcd-tv-32LG30.jsp . Click on the Support and then on the right hand side look for User's Manuals. Since the TV has a tuner for ATSC, NTSC, and Clear-QAM, the next question is what is your signal source? (analog, digital and unscrambled cable)

If you are using OTA, make sure that the input is set to Antenna. Use antennaweb.org or tvfool.com to check the direction to point your antenna and the appropriate antenna for your distance to the transmitter. antennaweb assumes an external antenna and is very conservative in the list of channels you should be able to receive. tvfool gives the stations available with different antennas. If you have several tvs connected to one source, you may need an amplifier in addition to the splitter. This also can help marginal signals come in since digital is either enough for the tuner to resolve or no signal. (Check splitters and amplifiers if you suddenly can't get a signal that you used to receive. Also check if the antenna has been turned.)

Menu > Channel > Auto Tuning or Manual Tuning. If Lock System is active, you will need the password. Auto Tuning only searches for digital or cable channels. The manual tuning option should provide the signal strength as well for digital stations (as well as letting you search for analog signals or all signals (digital, analog, cable).

Use the input Cable for coax cable connections. Other inputs will not allow you to search for channels since they are meant to be controlled by the set-top box feeding the system.

I hope this helps.

Are you connected to a digtal converter or just a digital antenna? If only to an antenna then yes you will most likely pick up one or two low power UHF stations that are still able to broadcast in analog.

I get no stations on my tv


Use an Antenna that Provides Good Reception of All Channels
  • Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
  • For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
  • Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
  • The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
  • Many antennas currently being sold as “HDTV Antennas,” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Check Your Connections
  • Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
  • Ensure that your components are plugged in and have their power turned on.
  • If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
Perform a Channel Scan
  • Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu. Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
  • Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
Adjust Your Antenna
  • Small adjustments to your antenna can make a big difference in the number of digital channels you can receive. If you have an indoor antenna, try elevating it and moving it closer to an exterior wall of your home. After adjusting your antenna, perform another channel scan to see if your reception is improved.
  • While adjusting your antenna, it may be helpful to access the “signal strength meter” on your digital-to-analog converter box or digital television to determine whether your adjustments are improving the signals’ strength. The signal strength meter is usually accessed through the menu feature on your remote control. Refer to the owner’s manual of your device for detailed instructions on how to access its signal strength meter. Remember to do another channel scan after you have adjusted your antenna.
  • Television stations broadcasting in digital use both the VHF band (channels 2-13) and UHF band (channels 14-51). Many indoor antennas use “rabbit ears” for the VHF band and a “loop” or “bow-tie” antenna for the UHF band. Make sure you are using an antenna that covers both the VHF and UHF bands and have connected it properly.
If You are Still Having Difficulty:
  • Until June 12, 2009, some stations will be operating at reduced power levels. If you are not receiving certain digital TV stations, this does not necessarily mean there is a problem with your antenna or digital-to-analog converter box or digital television. Check with the TV station to find out whether they are planning changes that will improve reception.
  • When an analog TV signal is weak or receives interference, static, snow, and distortion will often appear on the screen. Digital broadcasting will provide a clear picture; however, if the signal falls below a certain minimum strength, the picture can disappear. This “cliff effect” means that if you watch analog TV stations that have static and distortion, you may have to adjust or upgrade your antenna system.
  • Simple indoor antennas provide minimal performance that may not be suitable for your location. If you are unable to obtain satisfactory DTV reception with your current indoor antenna, you may wish to obtain an indoor antenna that includes features for better reception of UHF signals, as well as VHF, and/or an amplifier to boost the received signal (often referred to as an active indoor antenna).
  • Generally, an outdoor antenna will get better reception than an indoor antenna. However, the performance of outdoor antennas can degrade over time due to exposure to the weather. If you are having problems, check for loose or corroded wiring, broken antenna elements and that the antenna is pointed in the right direction.
  • Try to keep the length of wire between your antenna and digital-to-analog converter box or digital television as short as possible for best reception.
  • “Splitters” that are used to connect a single antenna to multiple digital-to-analog converter boxes or digital televisions reduce the amount of signal available to each device. If you are having problems, check whether reception is improved without the splitter. In some cases an “active” splitter that includes an amplifier can solve the problem.
  • If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” Consider using an “attenuator” or removing amplifiers to improve your reception.
  • If you decide to replace or upgrade your indoor or outdoor antenna, many types are available from electronics retail stores at a variety of prices. Websites such as www.antennaweb.org provide information on the locations of broadcast towers and the types of outdoor antennas appropriate for the stations you wish to receive. If you need assistance with upgrading your antenna system, check with a local antenna retailer or antenna installer.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Hope it may helps:

Don't get ABC or NBC local channels anymore


ATSC tuners ("D/A converters") pick up signals off the air just like old school television. It sounds like you are just not getting a signal of sufficient strength. A weak analog signal looks like a "snowy" picture, which most of us are used to. But, the new digital channels quickly go from a perfect picture to none at all. It's basically all-or-nothing.

Try attaching an antenna to your converter. I know you can buy a new antenna from your local big box electronics store which is labeled "Terrestrial HDTV" or something, but that really doesn't mean anything. You can use any old TV antenna. Even a quality FM antenna (with an F-Pin coax connection) may work just fine.

When setting up the antenna, keep in mind that different channels are transmitted from different towers, in different locations with different strengths. Move the antenna placement and position around (just like grandpa had to do). You may have to make a compromise to get the best signal for your favorite channels.
