I have A "Dell" E152FPc, and I have found an open transistor (Q201) on the Power Supply Board. My monitor comes on nice and bright for approximately 2 seconds, then goes dark; the power LED is steady. The voltage to the PWM IC is waky.
Before you try any hardware troubleshooting go to your control panel and turn off any power management options.

Have you tried hard booting it?
What I mean is, did you unplug it and plug back in?
