The main chip is a DK-1203.
I reverse engineered it a bit, found that it's pretty closely matches the example circuit in the data sheet I found ("FLYBACK TYPE SWITCH MODE POWER SUPPLY"), pic related.

D5 measures around 700 ohms in the direction that current can flow, so I suspect it's bad. Unfortunately there aren't any markings. I'll get a replacement and (try to) solder it on.

Can anyone help me identify the package size?
It's a 2 pin diode that measures 2.85x1.8mm, 3.85x1.8mm including the leads
