Re: hdmi 1 no signal on panasonic tv
So I take it that HDMI 1 and HDMI 2 were wired through the wall and not HDMI 3. If this is the case maybe reconnect from the wall the cable for HDMI 1 to the HDMI 3 port on the TV and leave HDMI 1 on the TV not connected. Or am I missing something you ask me to not ask about?
To be sure it is the TV port and not a cable or connection, connecting directly from the player or cable box to the port with a known good cable is recommended. If the port is bad, then hopefully it is still under warranty.
