    Hi Guillermo,

    Lamp does not start can be caused by anything: wrong schematic, poor PCB layout, wrong feedback signal, not enough VCC, poor compensation, etc. It is difficult for us to give you advice without detailed information. Please refer the flyback design example in the datasheet to double check you design. There is also an application note available http://www.ti.com/lit/an/slua078a/slua078a.pdf
