Just bought a house and moved in. I have plug the TV into the wall antenna socket and the TV comes up with the message 'weak or no signal' what could be the problem?

Pixellation is a weak and noisy signal coming in. Digital HD needs a good signal at the antenna socket on the back of the TV. You need to have good quality quad shield coax cable down from the antenna, and preferably crimped F-connectors at each plug and socket. You may even need a new digital antenna if you are making do with an older analogue one.

Your other stations will also improve.

You have antenna issues. Try raising the antenna some more or relocating to another spot where the signal strength is greater. Pixelation is a sign of a weak signal -

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)

Yes its antenna problem?maybe your house too closed signal your antenna is getting hard to find signal for your TV.

You must use a Outdoor Antenna to widen your signal range.

And also i suggest that you move you antenna outside your house or at your roof to be able to enhance the signal for your TV.

Hope my solution will help.

U follow the tv owner manual instuctions for scanning for the DTV free over the air broadcasting by the tv stations signal yet.Do that first,still have a message weak or no signals.Buy a newly design Digital antenna or have a roof antenna already hook it up to the tv,follow the owner manual rescan it again will have all DTV free over the air broadcasting tv channels.

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!

Is the antenna the correct one for your environment? Do you have the antenna pointed at the stations you want to receive? Use antennaweb.org or tvfool.com to get an idea of the location and likely channels you can receive at your location. Antennaweb assumes an outdoor antenna but is very conservative in the list of channels you can receive. (These may match the limits of the indoor antenna.) TVfool lists the stations and the appropriate antenna that will likely receive each station.

Tall trees and buildings will block the signal. Get the antenna as high as possible. Move the rabbit ears and UHF loop to maximize your signal strength. Then make sure the TV is set to use the OTA tuner (ATSC for digtal stations). (That may mean changing the source in the setup menu.)

Then scan for channels. Move your antenna or parts of it and rescan or edit the channel list. (For some TVs there is a weak signal setup option that will let you manually enter the station number (including sub-channel). Then it will provide the signal strength information as you move your antenna.)

I hope this helps. An amplifier may help you bring in weak stations with enough signal strength for the tv to see them.

reception issues require a better signal source, attic or roof antenna should solve your dilema
Samsung should stop at AV2 when something is plugged in the correct socket, if it doesn't check for a bad cable.

you would need to know if the tuner is picking up analog signals in the air well( stick a wire a little bit in the tuner connection to see if channels pick up good or use an antenna , if so there should not be a problem with the cable being hooked up to it , if there is a problem even with an antenna then the tuner is bad and will need to be replaced , and the cable could have caused it to go out , but make sure that the tuner is working or not first.
