How do I prevent my Samsung ln46C600F3FXZA from locking up?

You have to have at least one input, if no cable then from an antenna.

If you're using a cable box, you need to set the TV to Channel 3 or 4 and set it to cable input. The cable box does all the tuning.
If you set it to antenna, you must have some kind of antenna attached to get any channels.
With some cable services, you can connect directly to the cable bypassing the box, but most no longer work that way.

First make sure that your Input is TV. Use the Input button on the remote (to the right of 0) or on the side of the TV (lowest button). To watch OTA channels, after connecting the appropriate antenna for your location with a coaxial cable to your Antenna In port, press Menu then use the arrows to select the Setup submenu. Press Enter to access the submenu and select Installation. Then select Terrestrial and then Input Configuration. Here select Antenna as your input. Press Enter to save. Then scan for channels by returning to the Terrestrial sub menu and select Channel Program to scan all available channels.

Since digital signals are either sufficient for your tuner to interpret or give No Signal, you need to select your antenna and point it with care. Go to anntennaweb.org or tvfool.com to get information on the stations that you should be able to get in your location. Antennaweb assumes an outdoor antenna but still gives a conservative list of available stations. TVfool gives stations depending on the color code of the antenna (indoor, outdoor, amplified) and their directions. If you are sharing the antenna signal with multiple TVs, you may need an amplified splitter. (If you do have an amplifier, you may want to test removing it from the line and directly connecting the 37HL17 to the antenna. When amplifiers get damaged they can turn into signal filters which block the signal completely.)

If you have the correct antenna, check if another TV receives the stations. If so, you may have a bad tuner on the TV. (Some TVs have better tuners than others and pick up the stations even with lower signal strength.)

I hope this helps.

(I use an outdoor antenna and antennaweb indicates that I should only get the stations from 10 miles away. I actually get those from 30 miles away as well. When I set up a neighbor's TVs with indoor antennas, one only gets the stations 10 miles away and the other gets the stations that are 30 miles away. The two antennas couldn't be rotated to the same direction.)

Hello idmcintyre,
Don't worry, all you need to do is get a digital converter box. You can get one at most electronic stores, especially the ones that sell TV's. Remember that you still need your antenna. Your antenna needs to hook up to the converter box, and then the converter box needs to be connected to your TV. The converter box just changes the signal. I hope this helps, give me a feedback if it doesn't. Good luck.

You can buy an indoor antenna or you can mount one on your roof top. Find auto programm in the setup menu of the tv. Select antenna not cable and select auto program. The number of stations will depand on location. You may have to rotate the antenna. If this doesn't get you more than 3 stations you may have a tuner problem and need to replace the main board in the tv.

Try selecting the AIR/ANTENNA instead of CABLE in the on-screen menus. Do a scan for all channels. Make sure the input cable is secure and tight in the jack. You need a VHF/UHF antenna and try different positions of the antenna and redo the scan. Make sure you have selected the ATSC tuner as most TV air stations now are digital ATSC. The TV could be at fault/need to be repaired if nothing works or you could be too far away from any digital TV stations given the antenna you have. Possibly get a bigger antenna.

In the menu select Chan. Manager. Select Antenna if you are using an indoor or outdoor antenna. Select cable (1 or 2) if you have cable TV. Go to autoscan and select start. *NOTE* If you are using an antenna then you should be aware that this TV is not capable of getting broadcast digital stations. You will need a converter box and your box will do the channel changing.

Check that in the set up menu you have "cable " selected for cable/antenna or signal type and not "antenna"

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.
Exact information can be found in your Users Manual.

Hi,
It sounds like you haven't selected cable in the "pull-down" menu. You see, you physically have to tell your tv if you're selecting "over-the-air" programs(free), or cable. Select the cable option &
then run "auto-select". Your tv will go through it's steps & find your cable stations. I hope this helps.
