"No" message appears on player front.

Try using a hack code....

Try inserting a cd, almost all dvd players can play cds as well, if it displays the same message you may very well have a defective dvd player, if it plays then you may have a damaged disc. If it plays the cd try a mint condition dvd; also, I'll assume that you know better but in many cases if the dvd player is not defective users are simply loading dvds in upside down. If all this fails return your dvd player to the store or check the warrenty.

I hope this helps, good luck

This machine is a piece of ****. Just throw it at your least  favorite neighbor and go buy a sony, never had a problem with there's.
