Make sure the disk you put in the player is compatible with what is in the manual. Don't try to use disks you burned yourself when the manual does not say it is compatible with CD R or DVD R + or -
And when it is compatible with CD / DVD R, put the files on the disk in a format the player can read. Don't try to play MP4 disks, because almost no MP4 format is compatible with w DVD player.
You can make this player REGION FREE so all discs operate on it.
Power up, no disk in. Status says READ then INSERT DISC.
Press MENU (status reads invalid key icon)
Press 1 (status reads invalid key icon)
Press 9 Menu is displayed.
Press ENTER on the region, digit turns to "-"
Press ENTER again
Press EJECT to clear the special menu.
If you reset (unplug) the player for any reason - this will need to be re-entered.
Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong
you can try manually cleaning the laser lens ( gently wipe , do not press down hard , it is suspended by fine wires ) using a q-tip and a drop of that cleaning solution you got with the laser lens disc. ( fluff another q-tip a little ) then dry wipe it with another q-tip and try a disc.
you can look at the laser lens and see if you see the laser come on also to determine if that is working ( do not look directly into the laser ! )
if the laser works but it still does not read discs after cleaning it manually , then there is a problem with the focus coil on the laser or the signal board is bad

Try to use a different dvd because that one might not have been burned or made in the right format. If that doesn't work, then try blowing on the laser just in case there is dust on the lens causing it not to read the dvd properly. If that doesn't work, then you might need a new dvd player.
My Emerson won't play anything except DVD Movies, never has, wasn't suppose too. Make your movies in DVD Video format and it will read them fine (unless it's broke). I make movies all the time and play them back in mine. It reads DVD-R, DVD+R, and in duel layered. It will not read RW disks!
Man I've every problem you can imagine with DVD Players. I've found when the disk gets stuck, as long as it's not jammed. You can turn the unit off or unplug it. Plug it back in but DON'T TURN IT ON! Instead hit the eject button and the drive should open the drive without trying to read the disk.
