    Definitely a power failure somewhere. Do you get any headphone noise? I presume you turned volume up ... Also, checking it on battery power versus AC cord power may be useful.

    You could get lucky and find a connector unplugged.

    The service manual can be obtained for personal use online. Send email if you need a link.
