Dell Studio One 1909 Goes Black Right After Starup Each Time is it the inverter or power supply.
This is the First Place I've found that might seem to have an answer.
Thanks

from my own experience i can say that poor assembly and/or bad quality or lack of thermal paste for the graphic chip set on the motherboard is to blame!!!
i had a studio one 1909 which went black every time after a minute or so after start up.
i bought an inverter replace it and the PC worked for 3 days and started going black again.
this time before blaming the seller of the inverter i removed the heat-sink of the main chip (graphic chip-set)and found no thermal paste or a thermal paste of bad quality which have dried.
cleaned the heat sink and the chip applied good quality thermal paste (AC mx-2).
replaced the inverter back to the original one and voila!!
tha pc is working flawlessly for 3 days now.
it was probably a high temperature shut down of the graphic on board chip which causes the problem- at least in my case.
hope it helped someone.
