100% sure that LCD is okay?

Had this on many machines (Dell L502X, Acer 5740G, Acer 5750G, HP 6570b,...) and it was always a bad screen.

Problem with Laptop keyboard so replaced (No battery or AC connected during replacement)

Laptop booted fine first time, LCD display is now white but VGA and HDMI on external are fine

what Ive tried:

1. Checked cable seated and in place on MB (Still White)
2. Checked cable seated and in place on LCD Panel (Still White)
3. Reseated Ram and Cpu (Still White)
4. Test another Know working LCD Panel (still White)
5. Replace with new LCD cable (still White)
6. Reflowed GPU - (Still White)

If I connect either HDMI or VGA they display on external fine. What I have noticed is when these are connected the display turns from white to black but still no display

Power off I get voltages as
19.6v @ pins 1;2 & 3

Power On I get voltage as

19.6v @ pins 1;2 & 3
3.3v @ pins 7 -11 & 37

Any input would be very much appreciated
