motherboard not sending power to inverter ? Help !!

[xyz]

Have a strange problem... the motherboard no longer sends power to the inverter.
This is a result of there being a fault with the lcd cable..
Verfied this by trying on another baord and the motherboard on the other machine has the same problem now..

So it has to be a simple problem no...
Everything works excpet the nverter receices no power... the fuse at f7is blown on one board but replacing it causes the inverter to work then it fails again... possibly to do with something else in the circuit maybe.. a mosfet maybe ?

Any ideas ?
