Default Re: No Power Dell U2410 Monitor

Hi maxfox:

I have not ordered parts for my monitor yet, but I suspect one or both of ICs LD7575 (pwm controller) and SG9601.

I plan on replacing LD7575 first since it is only 8 pins and easy to solder. If that doesn't work then I'll try SG9601.

By all acounts, you have found or repaired the more obvious fails like the fusible resistor and mosfet transistors... I suspect the controller IC and pwm IC.

If you are getting 17V at VCC pins of those ICs then one or both of them is likely the issue since the input supply seems to be working.
