A Samsung SyncMaster 732NW Monitor came in last 3 weeks into my workshop after getting struck by lightning. This is what happen to the power supply board.
A bad capacitor, several diodes shorted, a blown fuse and blown SMPS Power Switch. Luckily the digital board, LCD and back-light still OK.
This is the heart of SMPS, the chopper (PWM) controller with built-in SenseFET by Fairchild.
Too many parts need to be replaced. So here is the shortcut. :-)
From the schematic diagram, we can see that it requires 2 types of power sources, 15VDC and 5.1VDC. Desktop power supply will do the job. It can supply 12VDC and 5VDC. Lower but tested working fine. 5VDC for the digital board and 12VDC for the back-light inverter.
A quick modification using 4-pin peripheral power connector. Several bulky components removed from the heavily damaged primary section.
There you go...
