    I have a problem with 2 of my DVD players. They read CDs fine but when
    a DVD is inserted, the DVD player doesn't even register that it has a
    disc in the machine. Can anyone help me fix this problem?
     

  2. (This assumes the discs aren't just dirty or damaged)

    Sure. Replace the laser pickups. The parts may well cost more than the whole
    players.
    Some require fairly extensive adjustments be done after replacement. This
    requires a service manual and a decent oscilloscope, and appropriate
    training to use them.

    The blessing and the curse is that the price of new (el cheapo) players has
    dropped so far that replacement is often FAR cheaper than repair.
    Unfortunately the quality of the new units being sold are often sub-par.
    Pioneer still seems to make a decent player.

  3. P.S.

    I just realized that your next question was likely going to be along the
    lines of, "How come it plays CD's but not DVD's if it's the laser?"

    Not only possible, but quite common. DVD players made the past several years
    have dual-element laser diodes; one side emits a laser frequency more
    compatible for CD, CD-R, etc while the other side is more compatible with
    DVD's. The DVD section of your 2 players' pickups have deteriorated or
    otherwise failed. This is an extremely common problem on DVD players.
