The above line means the computer detects that the TV is connected to the HDMI output.

Not true. The fact that timeout is zero means the screen saver is disabled.
Also, at the end of the xset output is this:
DPMS (Energy Star):
Standby: 7200 Suspend: 7200 Off: 14400
DPMS is Disabled
Which, in your case is what you want. It means the computer won't try to put the TV into suspend to save energy.

When you ran these commands, was the TV displaying the frontend? I ask because it looks to me like the TV should have been displaying the frontend when these commands were executed. If so, or if you don't know because the TV was off, wait until the problem occurs, then try running these commands. If the TV was on and was not displaying the frontend, then I don't think the problem is with the computer. In that case, I would suspect either the HDMI cable or the TV. Try replacing the HDMI cable. If that doesn't work, try another HDMI connector on the TV.
Yes, HDMI cables can go bad. I had to replace one a few months ago that had been fine for a couple of years. My symptoms were occasional flickering to black. I replaced the cable and the problem disappeared.
HTH,
