Hi Lew,
Quick update from here. Opened up my D3800 after another failure. Poked around with the heat gun which led me up the garden path a few times. Replaced caps around the rectifier to no avail, measured volts there in the fault mode, was fine. Then replaced a dodgy looking 2N3005, still no go. Poked around and could get the supply to switch between fault and normal by blowing hot air from the heat gun and then blowing cool air from my mouth around the LED positions. Reflowed solder around these components, and couldn't fault the supply again. Put it all back together and it died again.
I'll try again tomorrow. I haven't taken the front panel off yet to remove C10 and other components you mentioned. It's a rather tedious job, and even more so to put it back on again.
