Today I opened my E1705,but just now I realize I forgot to check what integrated circuit is used in inverter.
Maybe next time,or if somebody can tell us maybe we can find datasheet.
I take a look on what connections are between inverter - card - motherboard.
There are 12 wires
3 with power for inverter
4 with ground
5 with data
Bad news is that two of them I can't trace them (going deeper into video card)
Other three I can trace them until on-board missing connector...
