One possible cause is high value start up resistors in the PSU going

Here is another clue, sometimes it will startup when I press the tv
button (which switches between the normal aerial channels and the sky
digibix scrat connection, seems like your spike theory is gaining
ground...

Its been established in the flow of posts so far that your PSU is almost
certainly starting normally and the line O/P is very probably doing so
as well, it seems increasingly likely that the auto-greyscale circuit is
detecting an excessively worn CRT and shutting down the cathode drives.
On some sets an incorrectly set first anode can also confuse the g/s
circuit.


Why would it be doing that? What possible consumer benefit could be
obtained by greyscale shut down as you describe? Are you seriously saying
that the people at Panasonic will deliberately install a circuit that
shuts down the tv. I have never heard of such a thing, they could be sued
for that. Are you really sure about that???


This is starting to smack of a troll.


go away!
you already asserted that you will not help
why r u still here?
