DVD Player Doesn't Spin Up Disc

    Hi,

    I've got a Toshiba SD-1200 DVD player which won't spin up when you
    insert a disc in the tray. Originally, the spindle motor had a bad
    contact causing the motor not to spin at all with power applied. The
    motor spins now after cleaning the contacts and power is applied
    directly to the motor. But it won't spin when you connect the motor
    back to the circuit.

    By swapping the control board with my friend's working one, I was able
    to determine that the fault lies somewhere on the control board - the
    player works fine with the working control board installed.

    Can anyone tell me what part has likely failed on the control board
    which is likely to fix the player once the component is replaced?

    Thanks,
    John

    John:
    It might be a bad motor driver chip or circuitry..... or problem could be
    caused by a variety of things causing laser to not achieve focus.

    Since there was also a problem with the motor, a bad driver chip does
    sound like a possibility. Any laser problem would not have damaged
    the motor (or vice-versa).

    IC503 is the 5-channel motor driver. Power for the SPDL comes from that IC,
    it's a KA3032, Toshiba P/N 79040150. 48-pin surface mount, on the DVDM pcb.
    Most likely your problem. I'd replace the spindle motor with a new one if I
    were changing the IC simply because the IC costs more than the motor, and if
    that motor is drawing too much current it will just cook the new IC.

    Are spindle motors for DVD players available at a reasonable price? In
    reviewing some of the past postings about spindle motors in various
    newsgroups, it seems spindle motors are not sold as a discrete part by
    manufacturers. Instead, the motor is sold as part of the laser
    assembly. It seems like few people repair DVD players as a result
    because the laser assembly often costs as much or more than the
    original player itself when purchased from the manufacturer. This
    doesn't include labor, of course.

    What's the best way to unsolder a surface mount chip like this,
    without lifting traces? A hot air gun comes to mind. I'll practice on
    some scrap boards first, but thought I'd ask this before trying.

    Thanks to everyone responding to my post!

  6. It is rare to find spindle motors separately for DVD players. Pioneer offers
    them for some models. Toshiba doesn't sell them, but I was able to swap one
    from a bad-laser unit to one which only had a bad spindle motor just today.
    The entire subchassis was 130.00 wholesale ( I bet they sell a lot of
    those!) the used motor was 0.00.
