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)
what has happend between the working / non-working state ?
just a power cycle
video related updates ?
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?

Hi,
My HDMI to TV (Samsung) stopped working 2 days ago and I'm trying to find out how to test the port. This is a Fedora 33 (Rawhide) (x86_64) system. The cable is good... swapped with a known working cable. Directional 15' Saphire cables... have arrows and are pointing the right direction (away from the system, to the TV).
Any hints/tips/suggestions would be beyond GREATLY appreciated.
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:

xrandr -q => HDMI yes/no ?
see above
sound via HDMI and headphone output at the TV
Sound card is broken in the system. TV sound self test worked as did the picture self test.
what type of graphics device?
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 550M] (rev a1) (prog-if 00 [VGA controller])
Does the display settings panel show the other screen?
This is a KDE FC31 live system booted now. KDE system settings for the display does not show the TV.

Is this system a laptop? Does it have an Fn+KEY which may possibly disable the HDMI port? I had an Acer which did this years ago. Drove me crazy.

nouveau or proprietary NVidia drivers?
The live image would be using nouveau.
Had you done any updates between the two reboots? Did you try booting a different kernel from the boot menu?
