Can't find a datasheet either....
I'd suggest measuring across C307 (this is Vcc capacitor)
Or trace that to Vcc pin (from positive of C307)
Typical range, 13~18V to start, 10~15V stopping. Typical, 11~17V operating range.

Hmz strange. I tried to push the probe under the cap to get to the + and suddenly it clicked on and stayed on.
I took some quick readings and saw that i now have all the voltage i need on the canle going to the mainboard
( 17v / 5v / 4v)
Screen is still dark and i only get some yellow dots on the screen wich become more when i bent the screen. I turned it off and im going to remove the foot.

Er... you should not bend a plasma panel. It will crack. It is not like an LCD, it is not flexible at all!

With main board disconnected and all the jumpers in place, unplug LVDS cable linking main board and control board, then jumper the points marked EXT AUTO GEN on the control board.

Haha i dont bend it like you think i bend it. Im leaning it backwards.
Still strange that those voltages came back.
The Ysus does not get any voltages. ( upper left corner cable)
