Dear Intellectuals, I own a NSX-46GT1. I performed a channel search using the built-in tuner option. The TV scanned for channels and began playing the first channel. But, as luck would have it, we had a power loss and the TV went off. Now I no longer see the built-in tuner option in the system settings. I tried disconnecting the TV from the wall outlet, disconnecting and reconnecting the antenna wire from the TV and wall. But no luck. Can you help me find a way out? Thanks!!!
