urghhh! BAD NEWS FOR XENARC OWNERS:
I opened up a Xenarc panel and this is what I found:
The backlighting panel can be removed from the LCD assembly by removing the screws and the small ribbon cable on the side that connects the small LCD PCB to the LCD. You have to leave the bottom ribbo cables attached.
From the LCD side...
Metal perimeter to hold it all in place
1 layer of reflective sheet
2 thick layers of slightly reflective diffusion sheet
1 thin layer of diffusion sheet
then the killer:
the CCFL is a tiny 100mm stick that runs up the side of the screen and is joined to a 4mm thick screen sized piece of plastic with a silver backing material with dimples ont he top surface to break the light out.
the entire existing backlight would have to be removed. But that means the Xenarc must get 400cd/m2 with a tiny CCFL - mayeb it is down to that reflective 1st layer on the screen.
Will have a think
Gonna go out to pick some stuff up from work and then i will be back...
