Sizpack13/Samuel,
Thanks for responding.
This journal got jumbled somehow.
I'm currently booted from a Live Fedora 31 system. I did this in the hope that the monitor would work. It did NOT. When I first connected this TV (2 years ago?) I did nothing special... it just worked. I have been running with kernel option "nomodeset" for a long time. Tried removing that with NO change in behavior.
"stopped working" means: before power cycle, display worked perfectly, AFTER power cycle, TV had a box "NO SIGNAL" or "NO CONNECTION".
I switched IDENTICAL CABLES with no change in behavior. Cables ARE DIRECTIONAL (Saphire 15'). Connected properly, i.e., arrows on both ends pointing AWAY from the computer.
xrandr -q reports:
HDMI-1 disconnected (normal left inverted right x axis y axis)

just a power cycle

none that I know of.
> video related BIOS settings still okay ?
I made no changes.
> settings from the TV still okay (maybe a hidden FW update) ?
I made no changes or FW updates. How would that happen?

what means "stopped working" ?
AFAIK, "known working cable" is relative:
Got two boxes, both "working" with HDMI.
but exchanging the cables => one box: NO picture ...(sometimes)
No idea how to test a HDMI port, just some idea's:
what has happend between the working / non-working state ?
video related updates ?
video related BIOS settings still okay ?
settings from the TV still okay (maybe a hidden FW update) ?

see above

Sound card is broken in the system. TV sound self test worked as did the picture self test.

01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 550M] (rev a1) (prog-if 00 [VGA controller])

This is a KDE FC31 live system booted now. KDE system settings for the display does not show the TV.
