Need help with A1151 MacBook Pro

Recently bought a a1151 and found that one lead of coil 4r7(L8300) had come detached from logic board bringing the solder pad with it. The coil is right next to the plug where the cable that comes from the magsafe power board plugs in (j8290) and the battery cable plug in (j8250). When power button is pressed the optical drive makes a noise but does not boot. Think the coil has to do with back light. The lead that is damage is the single one, the other side has two leads and the seem to go some power chips (q301 and q302). If someone knows where the single side goes or has a schematic that would greatly help.
Thanks
