I have an lg tv model 37LC2DB - EC I lost all my channels and can not auto programme so I did a factory reset now it says not programmed how do I get my digital TVs channels back

if all you got when you did the auto setup was 18 channels, that is because that's all the channels that your tuner could pick up in your area. There is no additional settings you can make or changes that will give you additional programs without an improved antenna system. Without knowing what kind of antenna you have there's no way to suggest an improvement.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

hi. that:s be reset factory could do. if no you need a technician . good luck!

hi,
IT normally happens after factory reset is done. You need to reprogram the channels. Try the auto program (AUTO TUNING) Process.

1. On your remote commander " Press HOME or MENU button"
2. Scroll down to " SETTINGS or SET-UP"
3. Then to "CHANNEL SET-UP"
   
4. Select " AUTO PROGRAM " To Auto program your LCD TV and it's done..
   

It maybe that the TV needs to be completely reset. in the menu somewhere should be a setting to "restore factory settings" or "reset to default" something like that...

Try this and post the results...

By pressing menu botton on remote then chose setup/then channel setup before presssing auto tune or channell auto programm you may choose air or cable option then you can go for channel auto programming and your supposed to be done.
hope that will help you
have a nice day
