    Thank you all for your help. False alarm. We had pulled out the whitw plastic (maybe magnetic???) strip from the bottom of the slot near the laser lense. A friend told us to stuff it back into place, It all works fine now.

    Is the DVD or CD burned off a computer that you are trying to read or is it a prerecorded cd or dvd from the store?

It won't press the button even though the power is on


Since you don't indicate what you mean by "won't work", let me provide a few possibilities:

1) You close the door and you can hear the DVD spin, but no reaction on the screen other than some type of "loading" message. This indicates that the optics are attempting to read the DVD but are having difficulties. The operation may ultimately be successful and the DVD may start, but the movie will be unwatchable because of freezes etc. In this case, try cleaning the lens using a cotton swab and alcohol. A dirty lens can cause this.

2) You close the lid and do not hear the DVD spin. In this case, the optics can not even determine that a disc is in the machine. Again attempt to clean the lens. If that fails to at least cause the disc to spin, the optics have failed and need to be replaced.

3) Try a music CD. If that plays OK, but a DVD does not, then the optics are defective and need to be replaced. DVDs require a more powerful laser and will typically fail sooner than CD levels.

Hope this helps,

Dan

The dvd drawer won't open. it is "stuck" closed.


Hello

A stuck drawer indicates a jammed mechanism or the presence of a mechanical drawer lock.

Locate your DVD player's manual Eject button. It is usually a small hole located underneath the DVD drawer.

Insert a stiff wire-such as a paperclip or safety pin-into the hole. Push gently and the drawer should open partway. Gently pull the drawer the rest of the way open.

Cd tray will not stay closed it opens as soon as you close it


Hi and welcome to FixYa,

Offhand, 3 possibilities:
  • tray is not really reaching closed position, belt is loose/worn out (most likely), replacement required;
  • dirt on the laser/optics, false reading, the CD is thinking it has a CD inserted and when it can not read, it ejects. Clean with a CD disc cleaner (likely);
  • virus/malicious software (a possibility), scan/clean.
Good luck and Thank you for using FixYa.

Disc Error when I try to play a dvd LG DP781


Hi,

Sounds like either a dirty or weak laser/lens. Pls try cleaning with a CD disc cleaner or manually using cotton buds (if the eye is accessible).

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Bad disc


Try cleaning the lens yourself. Before taking drastic measures as replacing stuff, try cleaning the lens on the DVD/CD Drive. You will need to open the unit and also open the DVD/CD case. Make sure you do this while the unit is unplugged from a power source. Locate the lens that reads a dvd/cd. Now get a cotton swab and moisten it with isopropyl alcohol (rubbing alcohol) and gently rub the lens clean...use the other dry end of the cotton swab to rub it as well. Try not to use too much alcohol on the swab and not too much force when rubbing. Let it dry for a minute or 2 and screw the unit back into 1 piece. Moisture, cigarette smoke, insence smoke, and dust can cause a barrier between the DVD/CD and the reading lens and by doing this you will either fix the unit or know that it is a problem that will need replacing. Good luck!e lens yourself manually
