    Hi Edwin,

    I'm not sure about this HOT but you can try use BU2520AF and C5411. If it is hot then don't use it. If after sometimes the HOT turn warm then you can use it as replacement.

    HI Felix,

    Sorry no schematic on this model. You may need to find the schematic to find the HOT part number.
