Any S3 voltage present, or pulsing at least?

Please, STOP to quote an entire post, visible few centimeters above.

Do not confuse turned on board with working board!
Your board turns on at least.
Check now if you get S0 voltages, especially VCORE.
If present, check for USB activity.

The battery is not charged.. Is there a possible way to charge it outside the Mac ? Like externally ?
I think the battery is dead maybe ?

You need to confirm USB activity first, to know if board boots.
No reason to search video on a turned on board, but not booted.

Okay I will order such an USB Hub and inform you further :)

But if the Board Doesn't boot - what could cause such a Problem ?
