I hope someone can help me. I currently use an antenna in my attic to pick up free OTA channels on my VT60. Recently, many of these channels required a re-scan. It successfully completes the scan, but some of the channels are still black. After the scan, if I select "edit" I can scroll down and view these channels. However, the TV keeps reverting to the old signal when I'm out of the menu, even though the labels are correct.
I can't find any way to delete the old channels and start from scratch. Someone suggested unplugging the coaxial from the back and doing a re-scan, which I did, but that didn't solve the problem. Under "edit," the only options I'm aware of are to rename the channel or select yes or no if you want these channels displayed when using the up/down channel button on the remote.
I removed the names, selected no, then re-scanned. This didn't solve the problem, but now I have duplicate channels in there with no way of removing them. I'm afraid to do a reset, because I'll lose my professional calibration settings. I called Panasonic, but they no longer offer phone support for their televisions. If someone can come up with a solution, I'd really appreciate it.
