    Thanks for you reply and help and am going to either try a disk cleaner if that doesn't work will have to send it in for repair!

    I understand that your DVD player can also play CD. Then, the IC that is supposed to read CD is defective. Therefore you need a technician to troubleshoot and replace the defect.

That is a faulty lens. The lens reads DVD and CD on different laser beam frequencies. To read the TOC initial track the lens must focus on the laser beam reflected by the disk. If the lens is opaque, scratched or dirty, sometimes it can focus on DVD but not on CDs or the opposite.
Try using a cleaner disk, if that does not work buy a replacement drive. Today you can get a dual layer DVD RW for less than $30.

Testimonial: "Thanks very much for your help will try your tactic asap, thanks again!"

Buy your DVD/CD cleaner, and play it. The will clean the laser eye
of your CD. After playing the cleaner disc, play your CD. Clean your
CD disc with CD cleaning cloth.

Does it use DVD-R or DVD R discs ?

This model can not record. So you need to use a finalized disc - the listed spec is DVD-V (Region 1 or All). It also can't read DVD-ROM or DVD-RAM (trying this format can damage the unit).

If you have a DVD recorded on another machine and it isn't readable, check if the disc was finalized. Sometimes the brand of disc matters for playback of DVD-R or DVD+R discs. I've never found a rhyme or reason for some of these issues with one disc versus another.

I wish that I could be of more help.

When i put cd in tray it want play

Make sure your "CD" is readable. In other words a CD-ROM will not read a DVD.

Also, is this "CD" in retail format or is it a burned CD or a CD that someone made for you? If that is the case, then your computer may not be able to read the "CD".

Thanks.

When I put DVd in sounds like its loading then I get disc error playback not on this disk

Several possible causes
1. Laser read lens dirty - clean it
2. CD has become damaged & data cannot be read (does it read in other cd drives?)
3. Intermittent malfunction of laser read circuitry.
4. Process of elimination - if CD is readable on other drives, the problem is with DVD player. If cleaning does not solve the problem, the problem is DVD internal electronics.

Not reading dvd r or rw as writable disk

It sounds like you are having issues with all DVD writable disks. From the specs I was able to find online about your DVD writer, DVD+RW discs may not be compatible with the the drive. Make sure you are using DVD-RW (note the minus instead of +). I think you might need to reinstall your DVD drivers. This should solve the issue.

Various LG DVD Player

Some models of PIONEER cd players had radio frequency problems that caused them to work on and off. Are you near any radio or braodcast towers? Poorly shielded power supplies cause this as well. A weak laser diode in the pick-up assembly in model runs could be the problem. You might want to Google the model number and see if this is common for these units.
