    Dead, won't come on, led is on at standby, & just flashes at turn with
    remote, indicating SMPS is ok, & getting signal to turn on. Unplug
    connector CNZ04 from convergence, pop in speakers, tries to start, but
    shuts right down. Sanyo STK 394-250 IC's seem ok, & all fusible
    resistors check fine. Can't get at the board to do measurements,
    without removing it totally. No leaks.
    Anything common on this model? Dani.
