Re: TV and HDMI
I would attempt to debug with some other device.
Like maybe a camcorder with HDMI output. That
has two desirable properties. When run off batteries,
it floats electrically. When sending a playback signal
from some video you shot, it has no reason to assert
"Do Not Copy", nor use HDCP encryption. I would
use that as a test stimulus for the HDMI.
A standalone DVD player, might float electrically (use
a two-pronged power plug with no safety ground), but
it may use HDCP to encrypt the signal on the way to
the TV set.
Since you eventually get the ports to run, it isn't
a physical layer problem (damage).
And the TV OSD, may not be giving you as much diagnostic
information as it could. "No signal" for example, might not
mean "No signal", it might mean a signal is present, and
"I'm not allowed to play it". You can't rely on the TV
telling you everything it knows.
