Hello, I have a Dell Inspiron 6000 and i replace the fan on it. Now when i assembled the whole laptop back . The laptop boots up and i see the dell logo for a second then the screen goes black. No beeps or nothing. The first thing i tried was to see if it was the GPU so i plugged a vga cable but nothing happened no pictured. Then i unplug the lcd from the motherboard and plug in the vga and i see picture and it works normal. So can it be the inverted is mess up or did i burn the inverter when i was taking it apart.
