I have an APS-277 power supply that is completely dead on the secondary side. No STB, no anything.
170 at the primary caps. Doesn't not appear to be any transistors or diodes shorted.
I have found R6201 to be open. A 10ohm 1/2w. Based on continuity testing it appears to be across the primary caps (which feels strange). Cannot seem to find a schematic. I found sony_ge4a_cxa3809am_fa7700n_ba2901sf_sch.pdf which seems to be similar but not quite there.
Does it make sense for that 10ohm 1/2W to be running across those caps? Seems awful small if its meant to drain those big caps.
Maybe something going on with IC6201? ::Update:: IC6201 shorted D-S. Removed, above resistor connections no longer relevant. Guess ill replace this thing and see what happens.
