Bush Dac 90 Capacitive Dropper

That looks to be the answer here, Refugee. Typically straightforward, with just the two ceramic supply resistors, neither of which should need to be physically large - just a matter of doing the sums or better still and definitely easier, using the spreadsheet. Entirely endorse the choice of diode, too, having used them myself in power supplies.
Also like you Lawrence I haven't done much with TVs since I closed my repair business in the mid-80s so I guess you could say I'm out of touch; but I still don't recall a widespread use of wattless droppers.
