    Sony Vaio Backlight issue

    My wife has a Sony Vaio VGN-FZ 4000. Unfortunately, sometime last weekend the screen got cracked. So I browsed over to ebay and bought a new replacement screen. It came in today and I just got through installing it.

    Whenever I turn the laptop on I immediately see the typical Vaio splashscreen, then it goes black, and I hear it load into windows.

    I have a 42" lcd with HDMI I can hook up to the laptop to get a display, and if I mess with various display settings, or put the computer to sleep and wake it back up, the backlight will kick on and go right back off.

    I don't think this is an inverter issue as the cracked screen works just fine. I am hesitant to say it's a bad replacement either because I've googled around and have found a handful of people with this same issue, but their posts went unanswered.

    Any ideas? I've tried to r/r the generic display drivers, update the nvidia drivers, and multiple reboots. Nothing has worked. I just have a feeling this is a little issue and not a major hardware issue.

    As an added note, the original screen had two power adapters that plugs into the inverted. One blue and white cabled plug and one pink and white cabled plug. The sockets on the inverter itself are color coded.

    The replacement screen only has one power connector, pink and white, and it is plugged into the corresponding plug on the inverter.

    Help!!!

    Any time the connections or # of connectors don't match up, there's a really good chance you have the wrong replacement panel. It sounds to me like you don't have the correct panel for that particular model.
