    Selamat siang master-master semua,
    tadi pagi ane dapet servisan gemini 8520 no signal sos.
    Setelah saya buka ternyata sudah bekas blower sana-sini, trus customernya ngaku pernah masuk konter [​IMG]
    di cek di pojok bawah konektor bat ada bagian yang ilang, setelah ane cek di skema ternyata D903, ada yang tau fungsinya? trus bisa di akali dengan jumper atau gmn?

    copas aja bro semoga bener....

    TVS Diodes
    Littelfuse TVS Diodes are circuit protection devices designed to protect I/O interfaces, Vcc bus and other vulnerable circuits in telecommunications equipment, computers, industrial equipment and consumer electronics from high voltage transients induced by lightning, inductive load switching and electrostatic discharge (ESD). Their p-n junctions have much larger cross-sectional areas than those of normal diodes, allowing them to conduct large currents to ground without sustaining damage.

    kalo dari kode diode nya ESD jadi bisa diartiin sendiri yah bro saya takut salah>>

    salam SOS juga hehehe
