But then you have folk that want some iron clad guarantee that's it. Or another test.
Sorry but I can only give you my vote given the story and my experiences in repair.
A week ago there was weird noise ( like ffffffffff ) coming from near the screen and then it suddenly started blinking and then the screen went black (you can still see the items if you really look well with appropoate light) The noise stops when the screen goes dark... when I closed and opened the lid the image will go back up and then after 15 seconds (noise on) the screen will go dark again (noise off) I tried reducing the bightness which fixed the problem... screen worked fine for 24 hours then again same thing happened. Now the screen stays on for 1 second and then goes off and there is no fixing it
To top things off Dell customer serivce doesnt want to help me becayse warranty is over...
Backlight, Inverter, Screen.... what should I replace?
