This is a problem with the lens..
Get a lens cleaner CD with liquid and clean your DVD drive(just put two drops of liquid on CD and press play)
If this doesn't work you will need to replace the lens...The repair cost is not very high for replacing lens..

Wont recognise any disk

When you get no disk error, that is usually because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others.

In that case you will hear disk spinning, whirring and clicking, but the TOC (table of content track at start of CD/DVD will not be read, therefore the error.

Whe this problem is starting you may be able to read only CD, DVD or Blue ray, or for example only DVD-R and not +R , or only to read and not to write and so on. After more prolonged usage , often the unit goes losing the rest of functions, and ends up not reading anything at all.

If instead there is no noise, and disk does not spin at all , then there is a faulty motor, or the motor micro-switch is bad. This situation is far less common than the lens problem.

Try first using a CD/DVD or Blue ray lens cleaner disk to clean the lens. If that does not work you will need to disassemble the drive , and clean lens directly with q tips and isopropyl alcohol, or to replace the CD/DVD lens, or the whole drive unit.

Displays "No Disc"

It can be several reasons
1. Disk is upside down
2. Lens is durty. CD/DVD cleaning disk will help
3. Disk is in different formate (for instance NTSC for US but you trying to playback disk in PAL)
4. Disk has different region code (look is the dvd player and disk have the same code, or ALL Regions code)
Good Luck
