Mystery jumpers on 16102B

Cab anyone tell me what the 3 jumpers on the back of my 16102B are? - there is a little sticker over them that says “LPK01”. I have read various rescue articles on other Liteon burners that claim these jumpers can raise a dead burner from the dead but the location of those jumpers is by the power plug - mine are next to the digital audio outlet.

Thanks,

Steve
