Broken IC PWM TOP258PN 

IC PWM TOP258PN
Monitor Dell ST2220ld


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 broken. We have attempted to replace the IC TOP258PN. And we'll change the fuse. Monitor is ready.
