In the power supply with the symbol BN44-00611D, the PFC does not start, a diagram identical to this:
The system works on SEM3050, unfortunately not available, on the forum I found out that its replacement is the SPC7011F. I put it in, it came from a working power supply, but unfortunately the PFC does not start. The supply voltage appears cyclically during the measurements
on the leg 8, ok 9V, but I look with the oscilloscope and silence at OUT.
Are these actually replacements?
