I have tried two different antennas and the screen says that the signal is weak I bought the TV today

all channels? outdoor antenna? if indoor antenna try moving antenna around to find the best spot, also you need to know from which direction your signal is coming from and how far you're from tv station, if too far you may need a signal booster, and make sure your antenna is for digital signals. same goes for outdoor antennas.

If you are dealing with OTA signal, you need to check a few things yourself. First, check that your antenna hasn't rotated out of alignment with your local transmitters. If you have only recently gone to OTA TV, use http://www.antennaweb.org or http://www.tvfool.com to check where your antenna should be positioned. (tvfool.com gives a more complete list of channels for most areas. antennaweb gives a very conservative list, even though it assumes an outdoor antenna.) Check your antenna wire(s) for damage. Sometimes the center wire in RG-59/RG-6 gets damaged as the wire is connected to the port on the TV or jack. Make sure that the surrounding shielding isn't damaged. Try a new cable (particularly if the connector was recently added/replaced).

Next what type of antenna are you using? If you have an amplified antenna, check if the amplifier has power. If you can, disconnect the antenna from the amplifier and check if the signal has enough signal strength for the TV tuner. (Also remove any splitters for a similar test.) I've seen amplifiers get hit by a power surge and turn into filters that block the signal.

You may need a different antenna. Outdoor antennas are recommended if your stations are more than 20 miles away or there are tall buildings, mountains, or trees between you and the station transmitters.

Next, if possible, check if the tuner from another TV can pick up the signal. Different tuners have different sensitivity limits. If that is the case, try an amplifier on the incoming signal.

If none of these tips help, you may need a technician to check things out. I hope this helps.

Either the connector on the set is bad or something is burned out. Try connecting to a tv or ext antenna and see what happens.

Different TVs have different specs on the input signal and level. The Samsung may not have an input circuit as sensitive as your other set.
I had a similar problem and added an amplifier from the antenna feed. The amplifier has multiple outputs and now both sets work.
The coaxial cable you use is also important.
For your cabling RG6 is recommended.
I’ve seen installs with RG59, which is a thinner cable and very lossy. It should be used for short runs only (from a wall plate to the tv, if RG6 is too bulky)

Hi, congratulation on your new house!

The problem is obviously from your antenna. The TV is not recieving any reception from the antenna and that is why it is displaying 'weak or no signal'.

Cross check your antenna connection and make sure the antenna wire is intact.

Also, most antenna's come with a booster. The booster makes reception from the antenna very strong and the TV would be clear.

Lastly, is this a new antenna or were you using it in your old house?

Please give me a feed back.

Yours sincerely.

You usually hear "weak or no signal" when the tv's input is set to air. Check to see if changing the input might help. Or if you are using an antenna to get your tv, then maybe your antenna is not powerful enough. The new digital signal is weaker than the analog, so antennas that once worked might not work as well now. Hope this helps!

try a outdoor antenna on the roof for digital signal use.also the main digital PCB is defective which has the tuner on it if the antenna does not work.you may try taking the
tv to a friends house and see if the tv works better.

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.

Weak signal is a weak signal, so not sure what if anything you can do. Buy a satellite subscription???

To get any HDTV to work this is what you have to do;
CHANNEL section
1) Connect your antenna cable which you have done.
2) Go into the menu to the source option and select AIR/ANTENNA since you are using an antenna.
3) In the menu you will have to SCAN in the stations. This auto program will find all available stations.
Now you can watch tv by selecting the station you want.
The new generation of HDTV is different from the old analog sets. These have to be set up to work.
