How to fix no power on monitor dell st2420lb ?



Monitor Dell ST2420lb

chassis Monitor Dell ST2420lb

IC PWM on the power board ST2420lb

IC TOP258PN

The problem with this monitor does not turn on. After the open frame track and observe that the test voltage in the secondary voltage is not, of course, with the first section, I found that IC broke. We have attempted to replace the IC TOP258PN. And we'll change the fuse. Monitor is ready.
