    Default CD not spinning

    Ok technology geniuses, when I insert a cd into my cd player it doesn't spin and doesn't read the disc.

    What is the suggested route of action ?

    they mostly use similar spindle motors, but are fiddly to change if you can find another. getting the correct height etc can be difficult on some. If its a cheapish oldish one its probably landfill. But you never know. Alan might be able to advise if he saw it.

    It won't read if it can't spin the disc so to diagnose that as a laser fault is bizarre.

    First thing I do if this happens is open it up and see if there are any visible issues, something obvious and easily fixed without any skill, experience or technical knowledge. There have never been any so far but I still live in hope.

    On older Players, once the Tray has closed, the first thing that happens is that the Laser lights and then the Focus Coils are energised (usually three times on older players) so it appears to go up and down three times as it attempts to Focus on the inserted Disc.
    Once it gets enough light reflected from the disc a Focus Lock signal is generated, then, and only then is the Spindle servo activated.
    As technology moved on, some players did indeed give the Spindle Motor a kick before everything above happened. However, my first thought on older players is always the Laser.

    JVC did suffer from Spindle Motor failure. On an older player I would just change both anyway, once the actual cause has been discovered.

    I concur Jim ..
    I am a TV repair technician by trade and have done many replacement optical pickups in the past ..
    Jim is correct ..
    There needs to be an initial response from the pickup of the laser light reflected from the disc surface before there can be any response from the servo ..thus no disc startup.
    Certainly this is/was true of older CD players ..
    So like Jim ..I strongly suspect opu(laser) over spindle motor or servo..

    There is a test you can do for yourself re - the spindle/disc motor..
    The two connections to the motor have to be isolated ...and a 5 to 6v (battery is best) supply connected directly to the motor ..
    This should cause the motor to spin ..and you can run it forward and in reverse for a short period ..
    I wouldn't exceed a minute or so ..
    This overunning the motor briefly often cleans the crap from the internal brushes ..and will temporarily revive a poorly motor ..
    But if it does not spin at all ..
    consider the motor defective ..
    My money is still on the laser..

    potential for a bad connection/broken wire. The really old ones had better metal motors unlike some newer ones that a lot of it is plastic . Brushes usually go.

    budget cd players are cheap as chips at the mo due to the ahem...vinyl revival.
    my local cash gerarator is swimming with the plasticy facia types.

    having said that, I have a rather fine Cambridge audio CD4..."tuned by pink triangle" it proudly says on the back.....

    its yours for nowt if you can get to Nottingham anytime soon.
