Need value for R541 on JVC TV model AV-27920

  1. Hi,

    Just like the subject says, does anyone either have a schematic or know the
    value of R541 (in series with D541, also blown but identifyable) for a JVC
    27" TV model AV-27920?

    Everything else seems in order.

    Any help is appreciated and thanks in advance to those who reply.

    Best Regards,

  2. OK, found what I needed via the web. Thanks.
  3. If it feeds the vertical circuit you could try a 1 ohm or a 2.2 ohm. The
    rectifier needs to be a high-speed type.

    Yes, this mainly feeds power to vertical also one bit of other

    You have burned out vertical IC. Change LA7832, 100uF 35V capacitor
    with one with 105C spec near that vertical IC, RGP10J diode and this
    1.8 ohm resistor. The main reason for this blow up is that capacitor
    dry up then vertical IC self-destructs.

    The contact between heatsink and vertical IC needs a thin layer of
    heatsink grease.
