    just wanna add its just confusing. when i testing coil to ground i found 3.3v coil is shorted. not like 5v coil is not shorted. but checking volage 3.3v and 5v coil was good.

          thanks

          0.015 on my multimeter.

          i've tried to replaced power ic for 3.3v &5v. but now 3.3v is missing

          then put it back the old one. still 3.3v is missing. thats why lid light does't turn on........

            it's short circuit.
            without power ic, is it still short circuit?
            first, make sure the short circuit is gone, if it still short circuit.
            LID, I mean not the lid light, but a component that controlled lid to ec, usually 3 pin.

            my tips: apply external power supply(no more than 3v) to the coil, with your finger find the component that heat up. then component that heat up is the problem that make a short circuit.
