This television displays a strange image and sound distortion just
after it's been turned on, as shown in this 5 second video.

It may do this several times, and, rather disconcertingly, seems to
be slowly getting worse.
Note - the slight flickering is an artefact of the video recording.
I'm using a computer output to show the fault, but I get the same
behaviour on broadcast channels if the computer is completely
disconnected, and turned off.
I suspect a warming up effect. Any ideas?

Yup, that's High Voltage arcing around in there.
Ouch!
Might me a good idea to have some one that knows more
about it to take a look.
I've disconnected it from the mains. Later on today (to allow any caps
to discharge) I'll take the back off and see whether there's any
obvious reason for arcing - dead insects, loose connections.
Beyond that, I have the problem of deciding whether it's worth paying
to repair a 10 year old CRT TV 
Sylvia.
It's not worth having it fixed in my opinion..
If you can't correct the problem via a clean out, I suggest you start
looking for a LCD unit.
That would be my thought exactly.
