    Hello Mike,

    I found you gave the IC # of Dell 1901fp LCD, I think you are an expert on it. Now, my 1901fp is power on, but will be blank after several seconds. I replaced the FET (SSS 7N60B) with 7N60, but still same, I heard a noise comes from a ceramic capcitor (103M, 3KV). the power to data board is ok, because I can still see the pics after backlight is off.
    Could you give me some hint or clue where I should check.

Dell 20" LCD monitor enters power saver mode at startup and cannot wake it

Check your PC with another monitor to confirm if the PC is giiving the data required for start up. If not the monitor driver card can be faulty.
However if the PC works fine then the LCD is not starting you due failrue in the interface circuit of the monitor port that makes the PC trigger to boot up the system.
It can be a failure of this IC in this section.
