If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

Hold the power button down until the unit shuts off, wait 10 seconds then turn it on again.

Upon restarting, make sure to choose Start Normally if the startup failure menu comes up.

Make sure the fan, heatsink, vents are clean. Replace Thermal Paste if needed. Try a restore to a date before this issue. Have you done ANY updates? Any damage? Try rolling back the Graphics Driver. Is it a Nvidia Graphic Adapter?

Screen flashes white then goes black


Sounds like a ribbon cable to the top screen maybe damaged. Upon startup, the ds does a systems check, any kind of failure e.g. a ribbon cable or a faulty screen would cause the console to shut down again. Presuming everything else works charging etc this is most likely to be the problem.

Plasma no picture, fades to black from startup logo


UPDATE:
I finally isolated the problem, the problem has to do with the Y SUSTAINER BOARD not receiving enough/necessary voltage when turned on, while initially thinking it was just the yboard was the problem, i replaced the Y sus board with no success, with only further diagnosis, i discovered the board voltages coming from the powersupply, there are 5 voltages that relate to the Y sustainer board, VA, VSC, VS, VE, VSET. they all supply a certain voltages that all have to be supply the correct voltage in order for the y sustainer board to be working, well guess what, the VA line, which for my set needs 70volts, which upon startup quickly drops from 75volts to a jumpy 8.5-9.5 volts, which of course is nowhere near the 70 volts needed, so this quick drop in voltage is directly related to the screen fade upon startup, i found the problem now the real problem is finding a replacement power supply. hope this helsp anyone with similar issues.
