No gps after double short circuit XD on APM2.5

Hello,After a crash, i have reconnected neo-6m gps connector reversed polarity.This caused blow of both apm2.5 and gps 3,3v voltage regulators.Replaced it with biggest ones LD1117v33, because i can't find SMD type!This is a very terrible to see, but APM,Gps and all sensors back to work correctly!So, i decited to connect my Gimbal with Martinez V3 control board, with pitch control from A11 connector, now made another big error!!! XDI have inverted A11 signal ang GND in the gimbal control card, now i blow diode and fuse on the APM.Tested it with multimeter i have 0,7v after this components, so i have briged and all back on.Only one problem stay:Gps give no signal, mission planner give "No Gps"Test it from terminal it give only "………………………"Back to check power on apm and gps, i have 5.27v and 3.31v, gps red led is on but onboard green led won't flash and apm blue led stay off.Now, this is second APM board burned i want try to not buy tird!Can i try to repaire it?Tnx in advance.Tottero
