You need to boost your signal somehow, get a better antenna. nothing is wrong with the TV, this is a typical Dropout when signal is low.

Need to know how to change and setup for use of antenna


Purchase your UHF/VHF antenna. The antenna can also be purchased at most electronic and retail stores. Consult your list from Step 1 and see how powerfulicon1.png the over-the-air signals are for your specific address. Purchase your antenna based on the broadcasting power you need to receive a clear picture on your TV. You might be able to get away with an indoor antenna if your signal strength is strong enough. If not, you'll need to purchase an outdoor antenna.

  • 4 Install your antenna (or have it done professionally) according to the building codes of your area. If you must use an outdoor antenna, it is a good ideaicon1.png to have the antenna professionally installed. This ensures that it is properly grounded on your roof, not too close to electrical wiring and stable during inclement weather.
  • 5 Hook the converter box up to your television using the cable that came with it (F Cable). Hook your antenna up to the converter Box. Turn on your TV and converter box. Tune your TV to channel 3 and press "Scan" on the digital convert box. Allow the box to scan for your available channels.
  • 6 View your picture and adjust your antenna accordingly for the clearest over-the-air feed. You should only need to make adjustments once. If you are having a difficult time getting a clear picture, use a signal strength indicator to see where you receive the most powerful signal.

    Basically you are not going to get good quality TV reception on an internal antenna unless you live very close to the transmitter aerial with no significant metal structures (including buildings) in the way. You may get a slight improvement by placing the antenna near a window and away from any large pieces of metal or other electrical devices, especially any with a large magnetic field (anything with a motor in it). You may improve the signal / noise ratio by making sure that you have good quality, foil screened (satelite grade) cable between your antenna and TV set.
    If the building has a (shared) roof top antenna you might get a better signal, which can be boosted using an in-line signal amplifier from that - but only if it is pointed at the right transmitter. However, as you will be installing the amplifier close to your set it will (just like the amplified antenna you are using) also amplify any electrical interference picked up by the cable as it passes down through the building - including from cars outside.
    However your best bet is going to be cable or satelite TV

    Tv comes on cannot get a picture nor sound. followed instructions in manual regarding source , enter , picture, enter , channel, enter.etc., I can get to the menus but nothing else. It is not on cable...


    If you have an antenna, you are trying to receive off-the-air broadcasting. Remember that a couple of years ago the US switched to digital broadcasting and analog stations went off the air. Your TV does not have a digital tuner, so you need an digital-to-analog adapter if you want to receive anything.

    The US government had a program before the switch to help pay for the adapters, but that's long past now. Radio Shack sells them as do other retailers, and you can find them online as well.

    The adapter picks up the digital broadcasts and converts them to a channel 3 or 4 TV signal that the analog tuner in your TV can receive. Some models of converter also feature video and audio jacks so you can connect it as an AV source like a DVD player. Once you've hooked the antenna to the converter and the converter to the TV, you'll be able to watch your local channels again. Maybe, that is.

    The trouble with digital broadcasting is that signal strength makes a huge difference in reception. With analog, a weak signal would still give you a fuzzy but watchable picture. A weak digital signal may not even be detected, or you might get a picture that breaks up (pixelation) or freezes on the screen. You don't say what kind of antenna you have, but unless you're in or very close to a large city or near the station's transmitter, simple rabbit-ears may not be enough. Many people found after getting an adapter that they needed a better antenna, even something on the roof. In some areas (valleys, remote areas, places surrounded by many tall buildings, for instance) people found they could never get any channels. If you do in fact have a digital converter already (you didn't mention one), this could be the reason you can't get anything.

    Hope this helps you figure out what's wrong. Thanks for using Fixya!

    TV picture freezing


    digital signals do not fade out and get snowy like signals used to do ... if the signal gets too weak then it just freezes .. you might say its either perfect or frozen .. sometimes it gets blocky .. where some sections of the screen freeze while other sections continue .. what that means if you are using an antenna is .. you need a better antenna or better aim for the one you have .. outside is much better than inside but just rabbit ears are ok for strong signal areas .. you can aim the antenna based on a signal strength meter usually provided in HD receivers in the setup menu .. you can also get an antenna map from "www.antennaweb.org" .. that will show you what direction to point the thing for each channel and how strong each channel should be ... if you are using Cable instead of an antenna then you should have good signal strength but there is a problem called "Crest Factor" .. that becomes an issue when they put too many signals on a given cable .. the cable handles it ok as long as there is no damage (bad ends, water inside, animal chews, corrosion) but the cable box or receiver may be overloaded as thousands of signals drift in and out of phase ... thats a cable company problem that might be getting worse as more channels are added .. the results are that periodically the picture will freeze or pixelate .. you probably have to accept a little of that but more than a little gets really irritating ....off the air reception with an inside antenna (like rabbit ears) you will find that moving around the room can effect the signal for channels in the UHF range (most are) .. aiming the antenna and getting it as high as possible will minimize that problem.. make sure whatever antenna you use is designed for UHF as well as VHF .. the little circle often found between the two "rabbit ears" is actually the UHF part of the antenna .. it can be rotated for UHF channels while the big ears are aimed and adjusted for VHF .. antennaweb.org will tell you which is UHF and VHF ..

    The words "weak signal" flashes on screen at different places and do not receive a picture.


    seems like you are using an "off the air antenna" that receives weak signal, you may be too far from the station, go get a roof top amplifier antenna or subscribe to digital service from cable, satellite or at&t uverse. If you think your antenna is getting good signal, try to rescan your tv for available channel. Make sure your TV set up is correct, if you are using Off the air signal, your setting should be set at "Antenna or off the air", then rescan your TV. Normally on Satellite or cable box, you just watch it on video channel or component input, if you are using HDMI then tune to HDMI channel.
    Check your connection to make sure they are making good contact. If you can post your set up, I can better solve your problem.
    For a resource on "off the air" antenna, go to www.antennaweb.org for help.

    No Signal


    Make sure you have a good connection from the antenna to the converter box. Set your TV to channel 3 or 4.
    The converter won't improve reception in any way, and it's possible you might need to relocate your antenna or get an exterior antenna hooked up to improve the signal strength.
    If you have enough antenna cable, and you're only using rabbit ears, hang them out the window or up on a curtain rod and see if that improves things.
    Some people have good luck with the new digital style set-top antennas. I think you'll have best luck, though, with an old roof-top antenna that's set up to feed your converter.
    Best of luck to you!

    You gotta have a way to get signal to the tv . If you don't want a outside antenna use rabbit ears .After you hook them up hide them behind the tv then do a channel scan. If you don't pick up all the stations set them on top and scan again or get satillite or cable hd boxes.
