  • JBL 518S blown parts in autosense PCB-02

    Hi,

    My JBL subwoofer 518S is not working any more. After opening I noticed some blown uo parts in the autosense unit. The Problem is, that they are completely destroyed. That means, I cant't read, what kind of parts they used to be.
    Is there a circuit layout somewhere in the net? Or does somebody know which parts belong to those places?

    The unit is: AUTOSENSE PCB-02 P/N:015-070508-101ZR

    The blown up parts are at: Q3, Q4, R3, R5, R6, C4

    Thanks for your help.
