Not the LCD - inverter or what else?

    I am having some display issues and have (by means of the Genius bar) ruled out the GPU as the culprit. The problem is 2/3rds of the screen does not display correctly (is either dark or has lines of the general color as my wallpaper). I have to press approximately 4 inches from the bottom and 3 inches from the right side of the screen (while facing it and reaching around to the back) and it will flicker for a few seconds and then work for a while. This leads me to think it is the big ribbon cable in the back. I have it all taken apart with the inverter disconnected etc and the cable visually looks okay.

    So... where should I go from here in diagnosing it? I am new to laptop repair, and especially LCD repair.


    Useful info:

    MBP (non-unibody) 15.4in/2.4ghz Duo/2Gb
    LCD model number: LP154WP2

    I had this problem with my old MBP which had the same LG LCD. It's the LCD that's the problem. Replaced it myself for $200.

    Also, that LCD uses an LED backlight. There is no inverter.
