I am just curious if anybody has had any issues re-scanning channels with the Panasonics? I have Panasonic TH-42PD50U that is connected to a DISH 622 receiver, but I do watch terrestrial ATSC through it. As long as I was in the re-scanning mode I decided to re-scan the internal tuner on the TH-42PD50U. It was an interesting experience because the device seemed to freeze up. I unplugged AC power for a while, then powered back up and it still seemed frozen. I recalled that some people in my area (Minneapolis DMA) reported issues with Channel 25 having non-standard MPEG-2 audio and that some tuners could not decode it. That prompted me to disconnect the antenna coaxial feedline, re-scan to essentially clear out old channels, and then re-connect and scan them back in. I then disconnected the TH-42PD50U again and deselected channels 25-1 to 25-5. That seemed to take care of the problem. While I cannot verify for a fact that this was the source of the problem, it certainly does not seem coincidental to me. Granted, there are probably few other Panasonic owners that would have this issue, but I wanted to post this in case. If someone were unaware of what was happening, this could have caused considerable time and money trying to trouble shoot this and get it repaired.
