Are you sure that you've flashed ftf for Mini Pro? If you have unlocked bootloader you can try to install any custom kernel for Mini Pro to see that it isn't hardware related.

think the bootloader is locked as the phone is locked on a network, the screen is working fine as i have just swapped circuit boards over from my other phone and its ok, i bought this phone as not working anyway so i dont know what the problem is with it, i do know its the exact same problem as my sisters x10 mini pro (no LED, can connect fine to PC, but doesnt start up just vibrates once)

Which ftf did you flash? The 4.0.2.A.0.42 for xperia mini pro?

Did you use this rom and flashed in in flashmode?

Are you sure bootloader is locked? If it is unlocked, you could flash the stock gb kernel from sony and then install the rom, but only if you have an unlocked bootloader!
