'no disc' on DD-A500GX

The problem of your dvd is the optical lens, try to clean it using a cotton buds and wipe it very gently. Note be sure not to touch the optical lens. feel free to send feed back.Good day and best regards

Either a DVD with the wrong region code has been loaded, and your player doesn't recognise it, or you have inserted a disc which is either rewritable (or an incompatible format for your player), a blank DVD or CD, or the disc has not been finalised in a DVD recorder. It depends on the disc(s) you have, whether they are region coded or those using a compatible playback format (finalised DVD-Rs are the best as far as burned copies go).

Examples of incompatible formats for your player may include;
DVD-ROMs
DVD-RAMs (which are the wrong version/speed for your unit)
Mini-DVDs/CDs
CD-RWs
DVDs with a different region code to your player or rewritable discs

* When using shop-bought DVDs, including those purchased online, make sure their region code matches your player.

Hello,
The most common problem that causes a dvd player to not read discs is that the optical reading lens is dirty or the discs themselves are scratched or dirty. You can clean the optical lens in two ways:
1. You can purchase an inexpensive cleaning disc from wal-mart and most other stores that sell electronic products. You would simply follow the instructions on the cleaning disc and put the disc in the player and it will run through it's cleaning cycle as if the disc was a normal disc.

2. You can clean the optical lens manually. You can do this by unplugging and removing all power sources from the machine. You will need a couple of cu-tips and a small amount of rubbing alcohol. Open the player like you are going to insert a disc. You will see the optical lens which looks like the following picture



Take and pour a small amount of the rubbing alcohol into it's cap and lightly dip a cu-tip into the solution. Shake out any excess liquid from the cu-tip and then going in a circular motion, lightly clean the optical lens. Repeat this 3-4 times and then let the alcohol completely air dry. Be very careful to not put any excess pressure on the lens or allow any of the liquid to drip onto any other parts of the player's components. Let dry for 2-3 minutes before reconnecting any power source. Your optical reading lens should now be cleaned.

If however, you insert the disc and it is not spinning up, then the problem could be that the small spindle motor has malfunctioned or dirt or debris is keeping it from functioning properly (using a can of compressed air will usually clean the inside and usually remove the dirt or debris). If the spindle motor has gone out, then it would require replacement. The part itself is around $25-40 dollars, but it would require someone with the technical experience to replace it and the labor would probably be around $50-65 dollars for labor depending on the prices in your area.

The following is a labeled picture and you will be able to see the top of the spindle which the motor is located directly below that.



You can read in my tips and tricks for dvd players "the most common mechanical problems" for a more detailed list of mechanical failures that happen with dvds.

Try cleaning the dvds/cds and the optical reader first and see if that fixes your problem. Feel free to ask if you need any further assistance.

If you do not mind, could you please rate my help. I would greatly appreciate it. Thank You

Hi anternidrumm,

According to the site below, the drive can burn dual layers discs:

"The 20x DVD multi writer opens up new dimensions for flexible read and write functions. This high-performance DVD/CD-burner is able to read your DVDs at a speed of 16x and CDs at 48x. It also brings fascinating dynamics into play when writing your blank disks. Now it can even write DVD-R DL two layer media at 12x, while reaching a speed of up to 20x for DVD+R and DVD-R. DVD+R9 and DVD+RWs are processed at 8x and DVD-RWs at 6x. And DVD-RAM can be recorded with up to 12x DVD speed. So how fast can it burn my CDs, you might ask? Even here, with speeds of 48x (CD-R) and 32x (CD-RW), it’s at the top of its class."

try getting optical lense disc cleaner kit from walmart,best buy ETC. it should clean your lense if your lense is dirty it will not read the discs .

Hi,
    The optical lense needs to be replaced by new one.
    Thanks for using fixya.

It could be a couple things...
#1. Over time, dust and deposits can accumulate on the laser that reads the disc. In many cases, DVD players with this problem can still read CDs. You could try a DVD laser cleaner, which is usually a disc that has a tiny brush glued onto it. Run the cleaning disc 2 or 3 times, and try it again. Try both CDs and DVDs, since CDs are easier to read than a DVD.
2. After a DVD player has been used for awhile, another common problem is that the laser in the DVD player becomes misaligned, inhibiting its ability to read DVDs. In many cases, DVD players with this problem will still be able to read a CD. I'd try a cleaning disc first, since the only way to fix this problem is to bring the unit to a service center for repair.
Let me know what happens after you get the DVD laser cleaner and run it. Hope this helps.

Various issues can cause drives to occasionally balk at writing optical discs. These run the gamut of physical, hardware, and software troubles.

Inappropriate or dirty media may be to blame. Make sure to match the type of recordable disc to the drive, and check each disc for fingerprints or other contaminants. If a disc is dirty, wipe it with a clean, soft cloth in a straight line from the center hole outward. Try a quality optical drive cleaning disc if you suspect dust contamination on the drive’s laser lens.

Some discs don’t perform well with certain drives, even within their rated speeds. Try recording at a slower speed and then with a different brand of disc. Also, on PCs, verify that the temporary file storage area on the hard drive used by the burning software has enough free, defragmented space. Allocate at least 5GB for a DVD (9GB for a double-layer [DL] disc) and about 1GB for CD burning.

Did you try to clean lenses on laser head?

sounds like your dvd laser has failed if it reads other media as there are normaly 2 lasers one for reading cds and one for dvds try using a cleaning disc to clean the lenses
