Subject: HV supply from LCD Monitor

Greetings

I have a very small HV unit, salvaged from an LCD monitor.  I think it provided 
power to the (cold cathode?) backlight.

1) Looking at the way the transformer is wound (flat transformer - series of 
bobbins on HV side) and track/pin spacings at the "hot" end, it looks like this 
is designed to produce kV's.  Anyone know any ballpark figures for what similar 
devices put out?

2) The device has 7 pins on the logic side.  Is there any chance that this could 
be run just by connecting two of them?  Two of the pins are identifiable as 
ground (I assume 0V of either a +5V or +12V supply), leaving five others as 
unknowns.

Trying to map a tiny, double sided SMD board is not the easiest thing in the world!

Cheers

M
