    Write what's your power supply and that there are IC in your model.
    * and write what the matrix is applied
    pls.

    LG over the last few years has ceased to publish diagrams of power supply units from their TV.
    Itis necessary to rely on the schemes from their manufacturers ( if they give ? ) or solutions power supply PSU units on the basis of these applied IC

    Hola a todos, por favor, si alguien me puede ayudar con el esquemático de PCB EAY 60803101 de LG. Llega al taller con el fusible F102 abierto y el zener B68 en corto, al igual que el oscilador Viper 27H. Hago los reemplazos, pero no logro que la fuente oscile, por lo tanto, no hay standby. Agradezco mucho la ayuda que me puedan brindar.
