Sanken Electric Co Ltd.
became intermittent then
failed error 50 two falshing
red LED's. Query whaich part
is the triac?
Board tracing shows p/s board
in two isolated divisions, a
power side, and a logic side.
Between the two a multi-winding
txfmr, and 2 opto-couplers.
Is the triac on the power side
or the logic side? The parts
have Sanken logos, and there is
no reference to most of them on
the Sanken site. Nothing that
references as a triac.
A schematic of any LaserWriter
p/s pcb might give a handle
on the logic of the p/s.
