    Hello,

    I have a Panasonic SA-AK630 Shelf stereo system and the unit puts out barley audible audio. There is only incredibly feint or no audio coming from speakers or headphone jack.

    There is a fan that apparently is dead. Not spinning.

    I checked media source, Re-started, Checked speaker wire connections, checked for loose main and daughter boards and fried components ( basicalla visual inspection)

    But found nothing unusual

    Any Ideas on what the issue might be?

    thanks!!

    if your circuitry does not have "decent" thermal prot. there might be a lot of issues
    . . . but there has been and occasion where the digitally controlled volume locks to default level and can be only decreased -- once you do -- the cold reset ("wall" OFF/ON re-defaults)
    you should address local yellow pages on this
