a hammer and a screwdriver

It sounds a little ghetto, but you need to unplug you TV and then wedge a butter knife in there carefully and pull or push the tray out. Either the motor on you tray is out, or it is off track. Either way you can use a butter knife for a while until the DVD player gives out.

I dunno, try using a flathead screwdriver or a butter knife to pry it open while at the same time holding the eject button.

You might still be able to take it back without the box though if you have the receipt. Call Target and ask.
Also, there might be a manufacturer warranty that’s still good.

You might wanna try this. When videos used to get stuck in the VCR, I learned that if you unplug it for about 30 seconds or more that it will deaden the commands to the unit. Then when you plug it back in, the first command that you enter, it will take. Try it. It’s better than taking a screwdriver to it right off. It couldn’t hurt. You may also want to call an electronics store like Radio Shack or Circuit City. Sometimes they know tricks too. Good luck.

My car cd playerdoes the same thing. I use a pair of twezers & gently pull out the stuck cd

Unplug it and leave it unplugged for about 10 minutes. Then plug it back in and it should have forgotten why it wouldn’t open.

leave it up to the man of the house
