I suggest you try a disc cleaner. I suggest you try a disc cleaner.

Insert the disc and listen closely by placing your ear to close to
the drawer of the DVD player. After the disc tray has closed, you
should be able to hear the disc spinning. If you hear no such sound, it
is common that the disc is not spinning up, which is why you would
recieve a "No Disc" message when a disc has been inserted. In some
cases, it can be difficult to hear the disc spinning, so you could
remove the lid of the player to actually see if the disc spins.---------------------If this is the case, you could try to determine the cause of this,
which is usually the "hat" above the center of the disc is stuck and
needs to be repositioned to lay against the top surface of the DVD. If
you are uncomfortable doing this, you'll want to bring the DVD player
to a service center.


if it is an older DVD player, and I'm sure it has had its fair share of use.
Over time, dust and deposits can accumulate on the laser that reads the
disc. In many cases, DVD players with this problem can still read CDs.
You could try a DVD laser cleaner, which is usually a disc that has a
tiny brush glued onto it. Run the cleaning disc 2 or 3 times, and try
it again. Try both CDs and DVDs, since CDs are easier to read than a
DVD.


After a DVD player has been used for awhile, another common problem is
that the laser in the DVD player becomes misaligned, inhibiting its
ability to read DVDs. In many cases, DVD players with this problem will
still be able to read a CD. I'd try a cleaning disc first, since the
only way to fix this problem is to bring the unit to a service center
for repair.


There are other possibilities for the players failure, such as a
defective laser motor (the motor that moves the laser), bad spindle
motor (the motor that spins the disc), as will as other various circuit
falures that could be the cause.


Try all things you can do yourself to repair the unit. If none of them
are successful, you will need to have the unit repaired, or purchase a
new DVD player. As a general rule-of-thumb, if the unit repair cost
exceeds 2/3 the cost of a new comparable unit (in both features and
quality), then don't bother fixing it. You'd be better off with a new
player.
