Hi I don't think is your fly back did you check the
power supply. power allways fail if the audio
blows up check the zener doides coming from the power
to the audio out IC. if you have one shorted. you
never are going to gave power to the HV cause is going
to shut down. check your E board, and G board for
shorted zener doides good luck :Manuel
