Is R61 ok?
A couple of points I'll throw in: 1) Those 35V caps (C108 & C109) should be exploding if they're getting 50V on them, or at least bulging.
2) The two transformer windings are common to the fan circuit, maybe something weird there?
But for quick check, disconnect P8 & P9 (brown and brown/white), what AC voltage do you measure between those wires?
