None of the above choices .A wire may be broken .It is overheating .It may not be able to get a charge .
Why may the DVD player be no longer working ?
Stef 's DVD player sat right on top of it , completely covering the vents . I put small boxes under the DVD player to raise it up and unplugged the box to let it cool completely down , but to no avail . I called Comcast and they said that should n't matter .
