When trying to play a CD it shows: No Disc - Panasonic RX-D27 Silver, CD Radio Cassette, Remote Control Boombox

Try the DVD in another player, if it works fine, the problem is with your player, not the disc.

time to upgrade your cd player but first try using a cd player laser cleaner disc if that doesn't help then try buying a new cd player

Laser disc reader may be faulty

change your burn software and file formats /if there are music files/

When you turn on the unit the cd draw seams to open. I hear it making a noise like if it is trying to get ready to play. When you shut the draw it won't play, change tracts, or the disc thing to put in more disc wont work. Someone please help me

what happens when you try to play?

try some 3rd party software, nero, magiciso, poweriso,,,to burn discs,,,

Or
try using XP service pack 3..
good luck.

Have you tried cleaning the Lens? nd means No Disc, indicating that the Lens is not picking up the signal, and so is indicating a 'No Disc'
