Samsung hlp 4663w does not receive off air signal from roof antenna through antenna ports 1 or 2. Get cable signal just fine through same ports. Same antenna works fine on other tvs. Whats the problem and can it be fixed with loading factory settings?

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 powerful 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 idea 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.

Hello
If you are using this TV with Cable connection, the strength of cable signal is low. Contact the cable operator and ask him to put a signal booster at your premises. If you are using it with On Air transmissions receiving, include an antenna signal booster at the mast of your yagi antenna on roof. OK

Hi my name is Roety,
I can help you with your issue ,
The digital tuner is always on, you just need to run the autoprogram in the setup menu with a digital signal connected.
An antenna is ant or air signal
using Cable click cable when scanning in channels.
If using a cable box there is no need to scan channels.
if using an indoor antenna it may not pickup any (roof antenna is 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.

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.

May Be becouse Antenna On Top Of Roof Is to old, Plugging cord in wrong place plug in: In

Change the input to antenna.
If it says cable:
On your Samsung remote is a button that says antenna. You want it to say AIR. Air is an ATSC tuuner that allows you to receive over the air HD with a pair of rabbit ears.
If it says AIR:
If it says AIR and you still can't get the HD channels. In the menu it will say Channel. In that sub menu it will say autoprogram. Make sure you have an antenna connecte to AIR in the back of the set and autoprogram AIR only.

Any questions respond to this post and I will respond.
