What is your TV source? The Polaroid LCD-2000 only has a NTSC (analog) tuner. Most OTA stations switched to ATSC signals a few years ago and a converter box is required to watch the TV. (A few low power TV stations still broadcast in NTSC but you need to be fairly close to the transmitter to receive the channel.) If you have cable, check if they have migrated to digital cable (QAM for unencrypted channels). If that is the case, you'll need a cable box.

With a digital-to-analog OTA converter box, you can still lose station reception due to the signal strength cliff. Depending on your area, you may need an external antenna or to check the direction of the antenna. I know I have to rotate the outdoor antenna every so often. It shifts in high wind. Even if the antenna only moves 5 degrees, we will lose the signal for half of the stations.

I hope this helps.

The KV-32FS100 only has an analog tuner (NTSC). Unless there is a low-power analog station still broadcasting in your area, you will not be able to watch OTA stations. (I've got one in my area that barely comes in.) If your local cable still sends an analog signal, you won't need a set top box to watch that subscribed service.

Otherwise, you need a set top box to watch TV. A digital to analog converter (the boxes that were available with the government coupon before the switch over) will give you over the air stations. The basic models only provide SD output; there are a few HD models available. Otherwise, you can use a satellite reciever, cable box (for digital cable service), or something like the Boxee or Sling with tuner. (There are a few different models of the Boxee; one added a tuner with a USB dongle. The newest model of the Boxee has the ATSC tuner built in.)

Note: OTA digital signal quality is either a strong enough signal for the tuner or no signal will be present. You need to point the antenna in the correct direction to receive the signal from your local transmitters. The type of antenna and its placement will also change the number of watchable channels. You can use antennaweb.org or tvfool.com to get more information. Antennaweb assumes an outdoor antenna but gives a conservative list of stations. If the signal is split to several devices, you may need an amplifier to get a watchable signal. (Sometimes amplifiers fail and you won't receive any stations, so test without the splitter or amplifier by using a direct cable to one TV.)

I hope this helps.

What make and model of TV do you have? What is your signal source (OTA (indoor or outdoor antenna), cable, satellite)? How is the TV connected to the source?

The model is important since some "TVs" are actually only monitors and do not have tuners. Then you need to connect to a set top box to watch anything.

Assuming the TV has an ATSC (digital) tuner for OTA, check that your antenna is pointed in the correct direction for the stations in your area. Use antennaweb.org or tvfool.com to identify the direction. Antennaweb assumes an external antenna and gives a very conservative list of stations. TVfool tells you the type of antenna needed to get any station (assuming no trees or tall buildings that might block the signal). Depending on your TV, you will need to enter the menu in order to correctly set the incoming signal type and scan for channels. Digital signals are either enough for the tuner to interpret or not available. If your signal is split between several TVs you may need an amplifier to get enough signal. Sometimes, the amplifier may fail and filter out all stations in certain frequencies. (Older TVs often only had a NTSC tuner; there are very few NTSC stations still broadcasting. They are low-power and thus you may not be able to watch them if they are far away.)

If you have cable without a box, which type of cable signal is coming in? Digital cable is QAM and not all TVs have a clearQAM tuner (that reads the unencrypted signal).

If you are using a set top box, make sure to set the TV to the correct input (HDMI, component video, composite video, coax and the correct number if there are multiple inputs). Make sure that the box is also on. If the set top box requires the TV to be set to a specific channel (3,4,60), make sure to go to that channel.

I hope this helps.

(For the US, the digital OTA tuner is ATSC and QAM for cable. In other countries, different signal formats are used.)

Hi,
Looking at a diagram of the back of your TV I see that you have only one Coax input. You will need to plug either your antenna or the DirecTV in one of the other sources available on the back of the TV.
According to DirecTV's website, their box also uses composite video cables and depending on the age of that box, may have an HDMI connection also.
Looking at the back of your TV, the composite video cable input is the top two rows to the right of the Coax input you are currently using.
Once you have both connected to different inputs, you can use your remote to switch between the sources and watch whichever you like.

if the display says cable, it won't get over the air signal. switch the source to antenna, hook up an antenna and go through auto program sequence.

U have cable's or dish's boxs?unplug,replug the box for the software to down load to upgrade.Unplug,replug the tv.Go to the menu set for Air or Cable then rescan all channels

To get local over the air channels, you will need to connect an antenna as your signal source instead of Cable on the back of the set. Then you will have to go into the TV menu for signal source and select the Antenna/air option. Then you will have to go to the auto program/scan menu and scan in the stations. This may take a few minutes.
Now you can watch local stations for free.
I believe the FCC "must carry" rule require cable to carry local stations also.

on the back of your set
there may be a small switch someone with 2 or 3 different options

I don't know the menu system on your model, but you have to check that the tuner is in the proper mode. Also, some of the new TV set models cannot receive a standard analog TV signal from its tuner.

As for the distance from the transmitter sight, this depends mostly on the antenna quality, antenna location, the power output of the transmitter sight, compatiblity of the TV to the received signal, and also the capability of the TV's tuner.

Modern TV sets are really designed to be used with a satellite or cable TV box with their respective service.

Terrestrial TV is dying out, and in a matter of a number of years, it will be gone.
