I inserted a disc and it couldn't be ejected, but I was able to insert another dvd and it plays. The touch screen became not very sensitive and responsive. What happened to my first disc? And how can I eject it without opening up the unit?

Use DVD cleaner to clean the lence, it is dirty. Thank you for using Fixya.

If it happens with all discs, the motor "spin-up" system is broken. Best to buy a new one.

It's probably just dirty opticals. Try running a CD cleaning kit a couple of times.

i think the cd or dcd disc inside stuck-up you have to insert the tiny hole located at the dvd rom and insert a needle or something that is similiar or smaller of the hole size of that locted in your dvd rom.usually its new the LED blinking when opening or inserting the disc. and now you can now eject your disc manually regarding your question about it won't play a dvd try first to clean your DVD disc with a micro fiber cloth, avoid you'll scratch it, if still the same i think you're dvd room is defective.

get a dvd cleaner try using it first, if this will not help then you can manually clean the lens by using a cotton buds but this must be done carefully because the lens is sensitive.

Sounds like a bad pick up assy (Laser)

this is device do not play dvd-video, onli dvd-rom with maps for gps-navigation.

Hi, to open thje the disc tray , look for a tooth pick , insert small hole in front panel push and back until disc tray out. , motor belt need to replace.

Sounds like a thermal related problem (it's getting too hot). There's not alot you can do since it's likely a design flaw that is at the circuit level.
