I have a Panasonic 50PZ85U plasma TV and a Philips DVD player connected through HDMI. The PZ85U isn't automatically switching to the DVD input anymore when a disc loads in the player. Audio and video passes fine. Everything was working fine until I unplugged the power center which the TV and DVD player are both connected to. Power was interrupted for a few minutes. Nothing was moved, and no other connections were altered. When I plugged the power center back in and turned the TV on, the TV prompted me to go through an initial set up all over, including channel scan, which I declined. No settings seem to have changed. But the TV will not automatically switch to the DVD input and go to full screen mode as it did before. I checked the DVD player settings, and found only one that might affect this under HDMI set up - Easy Link - Auto Wake up TV ... which was still set to on. Per the manual when any setting or connection may have been changed, I tried unplugging the HDMI cable, turning everything off, plugging HDMI cable back in, turning the DVD player on and then the TV, but still no good. Viera Link was set to "ON," but I noticed in the manual it states if "standard HDMI equipment is used, set Viera Link to "OFF." So I did that, went through the reconnection/power-up sequence, but still no automatic input switching.
So I called Panasonic and described the HDMI auto input switching situation. She asked me how do I get my TV signal. I said, "Uh, over the air." She began by telling me that when the power is interrupted for a few minutes, all the settings are lost, and I need to do a channel scan all over. I knew I was facing an uphill struggle when she said that. I told her all my settings and channels appear to have been retained just fine. She then put me on hold for ten minutes while she talked to "a level 2 tech and a senior tech." She said that none of Panasonic's TV's automatically switch input's (!), that the DVD player is switching the input. I said, "But it's the TV that senses the signal and does the actual switching of the TV input, not the DVD player." She was adamant that there was no way this could be a problem or a setting issue with the TV, so that was that as far as Panasonic concierge was concerned.
Was the concierge blowing smoke, as I suspect, that the TV has nothing to do with the actual switching of inputs? It completely baffled me how she could say that. As I see it, the TV is what switches itself to the DVD input once it senses the signal from the DVD player, so the problem could be either with the DVD player, or the TV, with the higher likelihood being the TV. But how could she say that no Panasonic TV will automatically switch inputs, when it's an HDMI CEC industry standard? My question to all you knowledgeable people, before I go out and buy another DVD player in frustration, is there a setting I may have missed on the TV that may need resetting to allow the TV to automatically switch to DVD input? Is there something I need to do in a certain sequence in order to reestablish the communication? Since I am hooked up by HDMI, but not Viera Link, should my Viera Link setting be set to "On" or "Off?" I want to exhaust all possibilities before I call Panasonic back. Thanks so much for taking the time to read this.
