LCD Backlight Inverter question

Hi everyone,
I realize this isn't strictly stamp related but I know there
are some large brains here. 8^) I'm working on building an enclosure for a
small (4") TFT LCD video screen. I want to make the screen unit as small as
possible so I've seperated the driver board from the actual screen module
by extending the logic and power connections. This is working fine, but I
can only extend the lines going to the backlight HV transformer about 36" -
any longer and the backlight won't power up. My question: Is it possible to
extend the lines that run between the step up transformer and the
backlight. I realize that these carry fairly high voltage (350VAC?) Could I
make them ten feet long? What would be the best (safest) kind of cable for
this? Why can I only extend the lines going TO the transformer (which must
carry low voltage AC) such a short distance? I'm a bit baffled by this...
Sorry for the off topic post, Duncan
