Curtis TV DVD combo disc won't eject - LG 32LG40 32 in. LCD HDTV

Have you tried both the eject button on the DVD drive and the remote? Is there a disk jammed in the drive? Here is the manual:

most of the time there is a small hole near the eject button that you can unbend a paper clip and insert it into that will release the door.

here's a video.. it's a computer, but same principle:

Spinning up when it’s trying to read disc. Eventually it will eject the disc because it can’t read it :)

May I would recommend buying an external DVD player.

need to set source to dvd. doing so was not obvious or easy.

While hitting the eject button use a small flat screwdriver or butter knife to ease door open, probably the rubberband like belt broke or the gears jammed up!

Hello
Just open the top cover, and try to eject the disc inside.

Hello
Just switch OFF the set by its front panel power control switch, and then switch it On and press the eject button without any delay. Sometimes the tray will eject, and try to close. If so switch OFF the front panel power switch, while it is out, and take away the blu-ray disc. the switch it On. All will be ok then.

If it has been overloaded with too many dvd's, then you won't be able to eject them. You'll have to disassemble and remove the discs manually, if you are not comfortable doing this, call an electronics shop, most large ones (FutureShop, BestBuy) will preform repairs. Cheers!

says loading then ejects disc

Two possible scenarios: First the optical pick up assembly that read the disc has malfunctioned or the eject button is faulty. Either way it is just cheaper to replace the DVD player with a standalone dvd player connected to one the tv input(s). Too expensive to repair just the dvd player if it is tv/dvd combo. The cost for labor and parts is more expensive these days to repair tvs or dvd player. For around $30 you can just replace...much more cost effective.
