Laptop screen blacking out

[polive]

t's an Inspiron 1150. I originally was fixed the screen for a customer when it was going dark on him with a new inverter for the backlight. Two weeks later it blacked out again on the guy.

I offered to buy the laptop from him for $200. He was fed up with it. It's actually not a bad laptop, so I bought it from him thinking maybe the inverter had gone bad.

I just received the new inverter under warranty and it's blacking out after about 1 second. Before you even see the Windows startup. All you see is "Dell" pop up for a split second.

What else should I check? The CCFL? As of now it works if I connect to another external screen, but it kinda defeats the purpose of having a portable machine.

Hm. Sounds like the inverter is shorting itself out repeatedly.

You could try putting little pieces of electrical tape on the parts of the inverter where it touches the case, as well as putting little slivers of tape through the screw holes of the inverter.

You probably need a new inverter again, though.
