v4 won't eject!

Hi! I modded a v4 with M2 Pro (1.07 I believe). Everything were fine after installed. But I discovered it only can eject at the first time when I tried to play dvdr game. Now it won't eject at all! I did bridge 2 bios legs before. But I fixed it already. Any idea about this eject problem? Please help!:(

Sounds like you have blown fuse ps14 which is on the underneath of the board in the bottom corner.
when this blows in most cases it also blows the BA5815FM ic chip
this ic chip controls Laser Focus/Sled motor Drive/Eject
and to test the Ba chip has gone, on top of the chip is a small dot below this is leg 1 count along until you get to leg (the one after the large middle section) and hold a multi meter on pin 8 and a earth point if you have continunity, or have a buzzer on you meter and it sounds the chip has blown and needs to be changed

Thank for your help!:)
