D1 channel makes it sound like the tuner wasn't autoscanned at all.
D1 means Digital 1 or Channel 1. To be honest, it may be reverting back to tuner only mode if you bypassed the intial setup of the TV set, and it also sounds like your TV selects the Component Video input too....
And yes, Panasonic models have been "autosensing" ACTIVE inputs since 2007.
That means if there is a LIVE/ACTIVE signal on the input, it gets to be selected in the list of inputs.
But they can't block ALL inputs...they have to have a default, and it's usually the TV's Antenna input. I THINK when you have NO HDMI signal....it does look like it's Default setting is the COMPONENT input.
So....is the HDMI on the TV bad, or the HDMI on the New unit bad or possibly turned OFF in the user menu on the DMR?
You had the TV for some time now, it's not brand new is it? It looks like a 2006 model from the TV stand and cabinet.
Panasonic manuals look the same as they did 10 years ago. Consistent artistry of the front page. It's nice, but it's hard to know old from new.
Anyways, This is what we have to figure out. The HDMI. Is it bad on the TV or the DMR unit?
The only way I would know, is if I went out to my truck, grabbed my Panasonic Blu ray and cable and connected it to your TV set and checked to see if it worked.
So, do you happen to have any other HDMI equipped units in your home to try it? Or can you try your DMR box on another TV? And don't forget the cable either. Just because it's NEW....doesn't mean it couldn't have broke in shipping.
This whole system should have just been plug and play, but that TV ACTS like it's brand new and just has not been set up when it was first turned on. Sometimes if you bypass that, it misbehaves.
See if you can swap the two units with something else that uses HDMI. We have to figure out if the TV or DMR isn't working first.
