Compaq Evo laptop LCD Screen issues

Hi all
I have an Evo N800V and it is very sick.

Every alternate vertical line is dead and it has a blue tint to what's left
and it is unusable at full native resolution
The LCD is a 15" 1400x1050 part number 286871-001

Having done a lot of research and substituting of parts, I have diagnosed it
is the LCD signal cable (not the inverter one)
The ribbon must have a break in it somewhere.

Anyway, does anyone have a source for these. Compaq (HP) state it only ships
as part of the LCD (which makes it uneconomical to fix)

I think I can get hold of a multi-LCD ribbon pack but having given HP the
part number, they say they can get it but cannot tell me what it is suitable
for, or what models it is compatible with - it's just an anonymous part
number it seems!

Any advice gratefully accepted!
