This is from a Hansol/Multitech H950 monitor.
Power supply portion appears OK, however when
the inverter is activated, the backlights only flash
briefly (By strobing the backlight control I can see
that the image is being displayed). Looks like it's
not oscillating at all after power-on, or is shutting
down very quickly.

Schematics for this sort of thing are not available, they're considered
replace-only devices. You're on your own I'm afraid, fortunately they're
not very complex and can usually be repaired.
Sometimes a bad tube will be detected and the unit will behave in that
manner as well.
