A: Only for the EMI filter and bridge rectifier. The feedback network, PWM controller pinout, and standby circuit are different. Using Ver 12 will likely destroy U1.

Replacing a 10k resistor with a 1k because the diagram was wrong.

Often small SMD parts that blow when a MOSFET shorts. Conclusion

In the world of online electronics repair, unverified schematics are a gamble. A "verified" BM5291 Ver 13 schematic means that a technician has physically traced the PCB and confirmed that the diagram matches the actual component values and silk-screen labels on the board.

The BM5291 Ver 13 IC is a highly versatile device, suitable for a wide range of applications and use cases, including:
