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
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.-B
In Japanese transistor nomenclature, "A" and "B" are used to designate PNP, and "C" and "D" for NPN types

This rings some bells... When I repaired one of these chasis I was faced with the same problem. I ordered the "original" 2SD2335 and received a much bigger transistor (I belive was a PC monitor HOT), then I realized the original was not correctly labeled and used a BUT11AF as a replacement, that was a much better fit. It worked fine.
