Re: DVD player says there is no disc in the tray when...
Yes that could be the problem, pop the lid of the player. there are just a few screws on the back. then one little screw in side that holds a silver plate , this plate covers the eye.just clean it with a q-tip and some alcohol and that should clear up your problem. that is the first thing i do when i have that message.

Hello The Laser Pickup Unit's lens of your DVD player is dirty or dusty. Clean it. Just use a lens cleaning disc to clean it. Just buy one, if you haven't. It can be bought from most of the local electronic spare part selling shops at your town, and won't cost more. Play it at least two times. It will clean up the lens automatically. When the laser pickup units' lens is dirty, the laser beam that reflects from the disc will have a very low intesisty, and the mechanism alongwith its control circuits, will try to compensate this, by rotating the disc inserted at very high speed, and that is why you hear Hum from (within) the system. OK.
This could be a real easy fix actually. When you have a disk in the DVD player and it says "NO DISK" the 1 of 3 things is going on.
Make sure you have a non home made DVD. Some DVD players will not play DVD'S in certain formats.
If you have a normal DVD in the DVD player and are getting "NO Disk" then there is a real good possibility the lens is just so dirty that it is not recognizing your DVD at all. This happens a lot to all disk players that are neglected from the cleaning process. Get a disk player cleaner and run it through a few times until the disk is read again. Sometimes the lens is so dirty you have to try a few times just to get the cleaner disk itself to play just to do the actual cleaning. Make sure to run that cleaner disk through once a week. These disk cleaners "sweep" the lens and work well. You can get one at your local Best Buy for $8usd.
The last thing it could be is that somehow the lens has come out of alignment. Just a millimeter out of alignment is all it takes to not be able to read a disk and DVD players get bumped and knocked off the shelf easy. So this can happen often especially with the more smaller travel DVD player.
I would give it a good cleaning with a disk player cleaning. Those disks have little bristles on them that "sweep" the lens and clean it real well. Remember that if the lens is so dirty that it won't play any DVD you may need to run that cleaner disk a few times to get the lens back to normal working condition.
A lens cleaner disk should be ran one time a week to avoid problems with playing disks be it CD or DVD or Computer.
Sometimes players go bad so keep in mind this could be the problem as well but I have had the DVD player in my garage get so dirty I had to clean it a few times to get it to work normal.
It's most likely dirty, though it could be failing. The lasers have an average life span of 3 years, under normal use.
Several companies make CD/DVD laser lens cleaners. You want the kind with optical quality brushes on the bottom side. You simply put it in, let is spin up and play, then take it out. It may not play the first couple times you put it in, but it will be cleaning the lens and pickups.
If that doesn't do it, I'd start looking at sales for a new player.
Try selecting another disc to play, if the next disc plays, it may be the first disc that will not play, also make sure that it is not a 'burnt' copy, if it is....the copyrights may have prevented it from the format being proper. if second movie does not play, it may be the reader inside is dusty/damaged. Also look at dvd disc to make sure it is not smudged/scratched or dirty. take appropriate cleaning measure if it is smudged or dirty,
