Has anyone in the community had issues with the incessant "Open Input List" pop-up on the bottom of the screen on power-up? To reproduce: - You need the TV (65UB9500) connected to a single HDMI source via an AV receiver - Power on the source selected on the AV receiver - Power on the receiver, with the correct input selected - Power on the TV The TV will go through multiple handshaking "glitches" (video goes on, then off, then back on) while the audio is playing. At the end, the video will be showing. Twenty seconds later "Open input list" appears, saying that there's no video signal (except there is...) I've tried disabling SIMPLINK, HDMI control on the receiver side, everything. What seems to trigger the issue isn't so much the presence of video, but if the TV sees a source over HDMI where it can't identify the source. If you bring up the "input switcher" app -- you can get a description of the attached source over HDMI. The device, if it isn't populating the list, confuses the TV. Has anyone seen this before or addressed it?
