Download the user's guide and go to page # 19 for more info on how to set up the TV to the proper input to receive all the channels.
Let me know if you need further assistance.

Same thing with my vizio vx37l tv. Did you fix the problem bpakja? If so please let me know how.

Tested and verified solution:

1. Set Tuner Mode to "antenna".
2. Run a channel scan. Should get zero channels found.
3. Set Tuner Mode to "cable".
4. Run another channel scan.
5. Celebrate!

replace the remote, dah.......

first make sure the cable is running through you vcr then make sure you vcr is set to either channel 3 or one of the inputs

Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them. You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.

have you subscribed to HD via you cable carrier (Comcast, Adelphia, Directv, Dish)?

Do you have a lot loose connection inside tunner. Need be re solder. Do this and TV will be ready!!.

then you can try channel 3 or 4 if that does not work then you have to replace for a latest tv that does not use cable box.thes out of style
