My Sony DVP-NC675P Multi-disc DVD player has been working fine for two or three years. Last night it stopped playing DVD"S. I tried several DVD's including ones that had previously worked. There are no messages, the process just seems to stop once you hear the DVD begin to rotate.
Have you tried cleaning the laser at all?
here are some step by step instructions for cleaning it
Things You’ll Need:
Air Duster
Cleaning Disc
Q-Tips
Screw Driver
3 in 1 Oil
Step 1:
First you will want to start by, unplugging your DVD player from the wall and tv, and move it to a more suitable working environment, like a table or desk.
Step 2:
Examine the outside of the DVD
player, around the vents for the cooling fans, and look for any
excessive dust build up, if the vent area seems to have a small quilt
of dust on it, it has been way to long since you cleaned! You dont want
to blow this dust with the air duster, as it will spread back into the
DVD player, however, if your dust build up is light, you can begin by
blowing through the machine. If you open the drawer, on some models
this will allow you to blow all the way through the DVD player.
Step 3:
Next, you can put your cleaning disc in and relax as it plays through,
however, if you had the "Quilt 'O Dust" mentioned above, your dvd
player is most likely still not playing correctly. If the cleaning disc
played through, you can stop here, if you had the quilt of dust, you
will need to do a bit more thorough of a cleaning, continue to the next
step if this is your case, otherwise.. go watch a movie!
Step 4:
Ok, now for the fun part, and a crash course in electronics. We will
now disassemble your dvd player for a good clean. First looks around
the seams of the dvd player for the screw holes, and for security tape.
(There should be a piece of tape on the dvd player that would break if
the dvd player's case is opened, this will VOID YOUR WARRANTY, continue
only if you could care less about your warranty or its expired) Now
once you have made your decision to open it up anyways... remove the
screws on the bottom side, so that you are removing only the outer
casing of the DVD player. Now that you see all the insides of the dvd
player, start removing the heavy
dust collections around your vents by hand, after you have completed
this, you can go over all of the insides with the air duster, just be
sure not to tilt, shake, or hold the can upside down, the liquid
nitrogen that comes out can damage your electronics and your skin!
Step 5:
Once you have the inside blown down, you can get your rubbing alcohol
and a q-tip, dip your q-tip in the alcohol, and use this to wipe down
the laser, you can also use the alcohol on the rails that the laser is
guided on if there is dust here as well, do not use the alcohol on any
of the circuits, or the boards they are on, just the laser, the rails
it rides on, and if it has small belts on it, you can clean them and
around them with the alcohol.
Step 6:
Once this is wiped down, and you have let it dry (wont take but a
minute) get your 3-1 oil, and dip another qtip in it, and lightly brush
some on the rails the laser rides on for a smoother move, this may even
make your dvd player run a bit quieter, you can also use this on any
gears you may see that are attached to belts. Make sure not to get any
on or around the laser, or on any of the circuit boards, be very
careful.
Step 7:
Once you have done all of this, you can begin to put your DVD player
back together, once its together, you can run the cleaning disc,
however, this probably isnt necessary, as you just cleaned the laser
with alcohol. Your DVD player should now be restored to practically
new!
Please let me know if this doesn't solve your problem
well if the disc won't spin, then I would check the motor that spins it and see if its bad or if the wires attached to it are bad at all

I opened the DVD player and there was no dust at all. Nevertheless, I blew compressed air across the laser. I visualized the cleaning disc within the player and noted that it was not spinning. I gave it a little shove and it did spin properly. Then I tried the same with a regular DVD. It also would not spin until I gave it a shove. It then spun for about 30 seconds and stopped even though I pressed the "play" button.
The first suggestion did not solve this problem. Could you suggest something else?
