I have a Samsung 600 watt DVD Audio 5 DVD changer model number HTDS 610 it will not read the DVDs how do I get it to work

The system should work with CD DVD audio and video. Both, bought and burned ROM disks. Don't try to play Blue ray disks.
Firs you should try to plat a CD. Please use a bought one not a self burned, because from those you can't be sure the music is burned as it should. If the CD works, also put in a bought DVD.
If non works, your player is defect. I don't think you have the skills nor the equipment to see what is wrong and you can't solve any problem inside. But if the bought disks work, check the format on the other disks. They should be like the manual describes.

Lg dr275 does not recagnize any disk

This can be as simple as a dirty lens or more drastic like defecitve optics. If you can access the lens, try cleaning it using a cotton swab and alcohol. Next try playing a music CD. If the CD willplay OK, but hte DVD will not, then the optics are failing and will need to be replaced.

Keep us posted.

Says no disk

With the power turned off, open the DVD Player, and then open the top where you load the DVD into the player. Locate the laser lens and notice that the laser is attached to a transport assembly that moves the laser diagonally outward in a slot. 1. Slide this assembly outward to the end of its track. 2. Slide the assembly back inward to the closest inward position. 3. Repeat the process of sliding the assembly outward and then back inward.4. Put in a music CD and let it play all the way through. This helps to calibrate the laser head assembly movement. When the music CD is finished playing. 5. Put in a DVD, and you should have a working unit again This is a factory solution from Mintek that was given to a customer who ask for help with the forever loading disc problems. This solution may work on other models of portable DVD players. Most portable DVD players use this type of transport mechanism. Try this solution it might work for you. I hope this information helps you with your problem.

I have a portable dvd player model number mdp1030 the unit keeps saying no disk I have tried numerous disks same results.

then i think the lens is not able to read the disk.

and so i would suggest you to buy a disk cleaner CD and run it in your DVD player and then use your regular disks.

if this is not working then it is some internal fault in your DVD players lens.

With the power turned off, open the lid and then open the hatch where you put the DVD into. Locate the laser lens and notice that the laser lens is attached to an assembly that moves diagonally outward in a slot. First, slide this assembly outward. Second, slide it back inward. Now repeat, slide out then back in. Next, put in a music CD and let it play all the way through. (This re-calibrates the laser head assembly movement.) When the music CD is done playing, put in a DVD, you'll have a working unit again. I had to do it twice...

Portable dvd doesnt play movies

Try cleaning the lasers lens with an anti static cleaning wipe. I used " nice'n clean" that I had purchased from Walmart to clean my laptop screen. My dvd player started back playing after gently wiping the laser lens.
