    Lenovo ThinkPad T420 Bad Inverter?


    My laptop LCD has been out for awhile and I've been using with an external monitor, but I decided to fix the LCD so I ordered a new LCD screen for it. The lcd screen arrives, install it and picture still doesn't show up. I then thought maybe I just had a bad cable from motherboard to LCD so I replaced that.. still no luck.

    I can see a faint image in the background, but it's very dark. Same with my original screen.

    What's odd is before my original laptop would show a just scrambled picture of black and white-- which is why I originally thought it was LCD.

    What would the next step be? To order a inverter? Do the symptoms above sound like it's a bad inverter?
