Its a K7191 with a P538 board.
When I plug it in, I get 40VDC when I check the red wire on R301--R103 also heats up pretty sharply. So far:
Capkit done, flyback changed, IC4 checked=ok, R103=3.0ohm, D19-D22 checked and ok, C55 swapped with another one, reflowed a bunch of joints but they all looked ok anyways...
What else would keep my B+ down to 40V??
