Panasonic PV-D4734S displaying only "DVD-Video" splash screen?

In both VCR and DVD modes, the display to the TV is only the blue DVD-Video splash screen -- as though a DVD is not loaded. I can hear the audio fine, and the video part worked until now (9 whole months). Panasonic phone "support" said take it to repair shop; but I pay labor since it's more than 90 days old.

Even if you can't help me, beware. My unit is untouched since install in a no-kids household. It just broke out of the blue.
