I have an old Dell e173FPf lcd monitor that when i press the power button doesnt give any signal, no power light anything.

Can anyone provide me the schematic for this board for me to try to troubleshoot the problem?

Re: Dell e173FPf board schematic

start by changing the small cap near the middle with the red marker on it.
use low impedence high temperature parts
panasonic FR or rubicon ZL for example
if that gets it running and the panel looks o.k. then change the other caps too - they dont last in monitors usually

First of all thanks for the help, and the delay. I had other things more urgent to repair so i leave this behind.

I have found various problems:

1-The Mosfet was blown (replaced)
2-The resistors smd close to it were blown to (replaced)
3-The Pwm ic i dont know if it was blown but i replaced.
4 The TL 431 blown, (replaced)
5-the shotky diodes IC SR10-10 blown (replaced)

Until now, the monitor is not working i have the E173FP schematic but is not the same as mine E173FPf, without the schematic is not easy to troubleshoot.
