I'm currently working on a Tv with the ONWA chassis which refuses to
enter standby properly (line stage still runs). In the past on these
sets it was a matter of repalcing a couple of transistors, usually a
2SA1013 and 2SC2355. However this one uses, as Q507, a 2SD2335, which
is NPN I believe and which I'm having trouble finding. what else could
I use?

I've just sort of answered my own question .- contrary to the
information I had earlier, I have discovered that the 2SD2335 and
2SC2335 are both NPN, tho' the 2SC lacks the damper diode, I fitted it
and it seems OK. I don't think this application is very demanding and
it is possible the original was slightly over rated?? will keep under
observation.
