Yes. You can check your OTA signal strength by pressing the following buttons on the remote:
Menu > Support > Self Diagnosis > Signal information
Hi, I have the LN46C670 and I'm trying out the over-the-air antenna. Is there some way to see a signal strength meter on this TV? I found some info on other models having one but I can't find anything on mine. It would be really useful in gauging how the different channels compare. Thanks.
