My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof

You must connect an Antenna to use the AutoTune. A set of rabit-ears is sufficient for most areas: RE: the Digital (Free) TV singals are using the old UHF/VHF frequencies - so any antenna designed for Broadcast TV should work. Connect your antenna to the ANT/Cable connection then re-run the Auto-Tune again.

The advent of HD TV has allowed for a new round of hucksterism to occur in the TV antenna industry. The televison channel spectrum is the same as it always was but the signal modulation scheme employed now is "digital", which is for the better. Signal propagation is the same as it was and it is not necessary to buy a "digital" TV antenna unless you fidn it necessary to receive TV channels that have sprung up from new directions. VHF and UHF TV signals travel in straight lines and are the strongest when your receving antenna is "aimed" at the transmitter for that channel. Since transmitters are lcoarted all over the poalce, you can eoither use a mechanical antrenna rotator to position the antenna to aim the transmitter of choi ce or use multiple antennas aimed in various directions.

Genrally speaking, the "cheaper" antennas have fewer elements and are thereby less critical to aim. They have a broader beamwidth, so-to-speak, provideing less "gain" in a specific direction in favor or a larger average gain over a broader "angular displacement.

Digital TV signals are not prone to "ghosting" so an array of cheap antennas aimed in several directions will suffice to capture the digital TV signals in your local area. Amplifed antennas are poor substitutes for "real" (passive) antennas placed in attics or as high as possible outside. TV signals are blocked or absorbed by buildings, trees, and such and the signal intensity can vary with the weather and even when leaves are on the trees and when they are not. All your digital TV requires is enough signal in order to work. A small amplified antenna sitting atop your TV may work fine though the signasl is barely above the minimum threshold. When the weather grow wetter, that singal may be beleow threshold and you won't get that particular channel until there is less moisture in the air!
The same is ture, of course, for an antenna placed high up on the roof, but the odds are far better that it will work so much better than the tiny amplified antenna on the top of the television simply becaeu the TV suingal inside the house, at lower elevation, will be inherently weaker to begin with.

Hope this helps you decide.

Hello - Sure can, You do NOT need a converter box. The TV has digital tuners built in and all TV broadcasts are digital now.

You need to purchase and install an antenna based on how far you are from the actual broadcast towers and what kind of geography lies in between . Obviously I don't know where you live but for example; if you reside in a city where you are located within a few miles of the broadcast towers you could get by with an indoor rabbit ear antenna. Say you live in the suburbs of that city 10-20 miles away you could probably use a small attic or roof antenna. However, as in my case where I live approximately 35 miles away with some hills and buildings between me and the broadcast source I need to use a large roof antenna mounted on a tall mast.

The simplest way to find out what kind of antenna you need is to visit this LINK and use the "See Which TV Stations You Can Get on a Map" tool. This will give you a very good estimate of the antenna you need. Until then don't buy any more antennas.

When you get it setup right you will be very pleased. OTA (over the air) HD broadcasts are better in quaility than cable or satellite.

Enjoy and thanks for using Fix Ya

digital air signals are weak and fussy. They are easily lost by having trees or large buildings in the way too.
The best thing to do is install a long range roof top antenna and re program the set. Be sure to aim the antenna correctly. if you cannot use a roof top antenna you can try the indoor digital antennas,but less likely to work consistently

If you're in the US, you will no longer get antenna signals because the US has recently switched to digital. The TV you have does not have a digital tuner and you'll need to purchase a digital converter box that converts a band of analog signal to digital.

Buy a digital antena,or a roof antena set it up plug it in,the in hole said Input or Ant..Go to the menu select where said Cable or Air.Select Air for free Air Tv.Scan for channels.

we need more information:

1) Your city in Texas; so I can look up the stations and find what frequency's they are broadcasting their DTV on.

2) What kind of antenna do you have ?
VHF ? UHF ? Inside ? On the Roof ?

A couple things you can try:

- instead of having the TV AutoScan for channels, manually enter the channel for the TV stations not being received.

- call the TV station you're having trouble receiving: they will ask you where live, what kind of antenna you have etc..


but you really should have a 'roof mounted' antenna that is matched to youre reception needs.

Well what your problem is the antenna is not secured well enough to the roof. You really only have a couple options, you can secure the antenna better or just live with the fact that when it is windy your channels will be fuzzy.

well it's the same as the days of old, the antenna has a range of reception. the further the sations antenna, the lager your antenna must be. just because you bought an amplified antenna does not mean you will receive the deep fringe station. also the antenna must be UHF and VHF to receive the broadcast in digital. most of the braodcasters have gone with the UHF band because it is more stable for the bandwith of digital broadcast. the UHF band is very directional as well, so you must be pointing to the broadcasters antenna. no set top antenna will work if you are further than 15 miles of the broadcasters antenna. the roof top UHF/VHF antenna with a preamp is the way to go. I have tested every compact antenna and unless you live in the city that the broadcast generates you will get no reception with these. terks are junk, and any small amplified antenna does not work if you are in low lying areas. roof top, roof top,.....ROOF TOP!!!!!

is the antenna a UHF/ VHF type? most of the broadcasters are broadcasting in UHF for the digital, also an antenna pre amp will help tune in those distant stations. you must point the antenna in the area of the signal. if you are able to pick up 35% of the singal or better, you will have a picture.
