I can email you a pdf of the service manual if that helps? According to the parts list in the manual the resistor is 1k 1w R830 and the diode is D809, I've attached a screenshot of the diode list.

The Diode in your parts list has a different number to what I posted above, having said that I did just look at the 1st BE3D diagram I came across on my hard drive, I don't know if yours or mine are an uprated type.

As I say even the replacement original type never seem to cause any repeat problems provided it was stood off of the PCB by a couple of mm.

I never had that blue ceramic cap fail either. Or ever had any repeats after replacing diode and safety res.

Thanks, but I probably already have it.
It is just I have a large amount of manuals on this PC by many makes arranged into folders by manufacturers name, I am just lazy and looked at a generic Chassis type above, actually the 28 inch similar version of your set.

What happens if you leave the set on for 10 mins?
To me, a Sony with no raster usually suggests AKB blanking the pic due to worn tube...

Hi Ben,
I left the set on for over an hour yesterday but nothing changed.

Can this thread be closed please? The TV has a new home with a mate of mine who collects Trinitron TVs.
Thanks very much for the advice and suggestions for it, much appreciated.
