I have an inverter board with a hard wired 50mm x 3mm CCFL. Picture is

and larger version at

and schematic I drew based on it:
http://personalpages.tds.net/~wilykat/schem.png (transformer coil
diagram unknown but it's drawn by the pin number)
Transformer has no marking other than high voltage. I am not able to
figure out the wiring diagram of the transformer without de-soldering
and removing it. 2 transistors are D1616, resistors are aprox 1/16w
SMD. Inductor has no marking either but it appears to have iron core.
Capacitor on the primary side has marking 1J100, and one on secondary
side has marking 22 and 3KV
Any idea what is the supply voltage? I think the typical inverter
voltage of 12v is too much as the board looks like it may be from a
small flash light type device.
TIA
