Hey guys I've got a Sony Vaio all in one... I've had it for a couple of years now and a couple of months back the screen went all black on me. I can hold a powerful flashlight up to the screen and it works but, you the back-light doesn't work. The weird thing is.... when you boot it up the back-light is on for a couple of seconds and then it just turns itself off. I thought it could have been the inverter, but I replaced it and it didn't help...
