The setup: an elderly Humax HDR-FOX T2 feeding a fairly new Panasonic T-42MZ800B TV via HDMI 1. Headphone output from the TV feeding a
Pioneer HI-FI system X-CM56/X sound system. All three in 'stand by'
mode when not in use.

Switch-on sequence: Pioneer - Humax - Panasonic.

The problem just recently started; a few seconds after switch-on, the
Humax PVR switches itself off. Pressing the 'power' button brings it
back on again and it's fine after that. Not tried altering the switch
on sequence.

Not a big problem, only a minor irritation, but I'm more concerned
that it's going slowly to get worse; but has anyone any suggestions as
to what may be happening?

If the PVR does fail irretrievably, what would be a good replacement
PVR with similar capabilities to the HDR Fox-T2 these days?

Any software updates recently? Out-of-interest, can you change to HDMI 2
(or even 3) and see if the problem occurs?

I had an issue about 10 years ago with my Panasonic TV and PVR, in that
the PVR switched the TV to the PVR's HDMI input whenever it came out of
standby for timer recording, so interrupting anything I was watching on
TV at the time.

Panasonic support suggested changing from HDMI1 to HDMI2, and that
solved the problem. Rather confusingly, Panasonic's explanation for this
was "the HDMI2 socket of your television will be the most sensitive one
to any signal it may receive from any external device connected to it."
If it was the most sensitive, I'd have thought it was more likely than
HDMI1 to respond to any signal from the PVR!

(NB I downloaded your TV manual and for a Panasonic manual thought it
was rather poor in that it didn't show exactly where the HDMI
connections were and what, if anything, was the difference between them)

If the PVR does fail irretrievably, what would be a good replacement
PVR with similar capabilities to the HDR Fox-T2 these days?

If you find any good PVR - satellite or Freeview - you'll have done
well, as it all seems to be moving to streaming today. :-(

Caps dying, don't have to be just in the power supply.
Capacitor failures can be via stress (PSU output caps
and ripple current), but in the Bad Cap era, simple
chemistry problems caused all of them to fail. There could
be failures all over the place.

https://www.mig-welding.co.uk/forum/attachments/s6003733-jpg.315498/

There is an open frame power supply in this example, so a dropped
tool can touch mains. If you were debugging the logic with the
power on, you'd try to cover the power supply area so a dropped
tool isn't an instant disaster. Otherwise, if inspecting inside,
just unplug it to make it safe. Usually, the capacitors drain
pretty quickly.

https://www.mig-welding.co.uk/forum/attachments/s6003736a-jpg.315500/

( https://www.mig-welding.co.uk/forum/threads/blown-capacitors-in-a-tv-digital-video-recorder.116723/ )

On SMPS, a failed capacitor can overload an adjacent MOSFET and
inductor, burning them. The main problem with this, is the
damage can be bad enough, you can't get a part number off the
items, to acquire replacements.

As a capacitor is circling the drain, a little puff of gray smoke
will come out of them at startup. If you see that, it's time to
stop using the item, until you replace the caps in it.

The crack in the top, can leak a brown liquid. The liquid can corrode
the copper tracks. With severe enough damage of that kind, an item
can be a write-off. If the capacitor has dried out, there might be
(less) liquid to pour down the side of it.

There's a particular capacitor that often fails. I replaced it in mine and
it's been fine ever since.

It's surface mount, but I rep;aced it with an axial lead one as it was
easier.

Streaming has killed the market for PVRs, or shrunk it considerably,
so manufacturers are not rushing to develop new models like they used
to.
The Humax Aura was released at the end of 2020 and is still available, remaining the only consumer PVR with three tuners.
(I have an Aura, from 2020, that I'm very happy with, but a few months
ago it started rebooting on switch-on, and powering back on during
switch-off, issues that I fixed by changing the switch-on/off
sequences on my Harmony remote.)

Thanks Bob. That looks suspiciously like the fault I'm seeing. When it
becomes an unbearable nuisance, I'll give it a try.

It's an easy fix. I think I had to remove something inside to improve
access, but that was simple too.

I found I was having to have several goes by the time I decided to fix it.

Wahey! Fixed it! Now working as it used to, with no repeated re-boots.
A bit of a fiddle though. My soldering skills are pretty minimal, and
the components on printed circuit boards are so tiny these days...

Thanks once again for your help.

Just leave the Hummy in standby, apart from when you want to
watch a recorded program.

Otherwise just use the Panny as a normal TV

Which could lead to more components or the hard disk failing.

I once had a Topfield PVR and when one of the power supply capacitors
started to fail it started to take down the 5V supply but initially not
enough to stop the box working. The 5V output was the feedback reference
for the switched mode supply which attempted to compensate by driving
harder causing other power supply voltages to rise. If the capacitor in
the 5V output continued to fail one of the other supply voltages became
so high (by an extra 50%) it took out a transistor responsible for
supply 20V(ish) to the tuners.
