    I tried replacing the laser unit but a couple of parts fell out as I was taking it apart and I couldn't figure out where they went. Does anyone have a schematic for the NEC 6500A DVD +/- RW? I could take pictues if someone could identify they and tell me where they go.

As DVD Burners are so cheap, it is much more economical to buy a new burner and install it (also much easier!).

To replace the burner - you open the case - disconnect the cables to the drive - remove 4 screws holding it in (2 on each side) - then slide it out the front. Rplacement is a reversal of teh above instructions.

BEWARE - Static electricity will kill ANY electronic component that gets zapped. Make sure you earth yorself before you touch anything inside the case and try to keep yourself earthed by keeping contact with your arms and the chassis - including when you remove and replace the cables!

Basically a very easy process to complete as long as you do not Zap anything.

Good luck.

How do i fix the dvd blue ray 3d player to load the dvd?


Most likely the laser is failing , try an audio CD if it works then it is a bad laser. A cd has much less data to read.

My Sylvania portable dvd keeps cuting on and off everytime I put a movie in but the movie never plays it just says loading and starts cutting on and off


Try putting an audio CD in, if it works fine thats a very good indicator that the laser is going/is bad. A audio CD has much less data to read so it's able to keep up, but not with the DVD.

When I insert myDVD disc, the screen shows loading for a minute or so--then reads incorrect disc and bad on the player. This is a disc I have used before and has the label that shows it is the disc this...


Hi,
It seems that optical laser block gets fail to read data on disc and possible cause could be dirty/ clogged lens or optical laser block failure.
Put lens cleaning disc in unit to clean optical lens and check DVD playback, if that does not solve the issue then optical laser block would be defective and requires replacement that would cost approx new player price.
Hope these info will help.
Thanks.

The dvd is not loading and will not play. the cds are working fine.


Hi,

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Regards.

No Disc-alert. Will not play any DVD's. Will not run lens cleaner disc. disc's spin. thank you


Discs spinning after being loaded, that's a positive sign, but 'No READ' or 'No Disc' usually means the laser has failed or its output is too weak to read DVDs (DVD players tend to spin discs at a faster speed with a higher read rate than CD decks (obviously to read the video data as well as audio per disc, the optical/laser voltage rating is higher for DVD). So they are more likely to fail quicker than CD lasers but not always.

In short, since the unit is only a player, and may not be brand new or under any warranty, consider replacing it with a new unit or perhaps a DVD recorder (or even a Blu-Ray player - as they are becoming cheaper to buy now) - the cost of repairs/parts for this one would be higher than a new one and not economical, although you can always submit it to a service centre and get a quote (and a second opinion) on the likely cost(s) of parts/repairs involved. It won't be cheap, trust me.

When we put in a disc it comes up no disc and does not play (DVD and CD)


This is a laser pickup assembly problem caused by the laser becoming weaker overtime, or a pladder motor malfunction that the cd/dvd sits on, one possible solution is to clean the laser pickup lens with a Q-Tip and rubbing alcohol. If that fails! the assembly will need replacement "very expensive" or replace your machine "much cheaper"

My LG CDRW Model GCE-8520B writes the cd but after writing when u verify the data the cd is still empty


The laser inside the unit that "burns" onto the CD has failed.
For $40, buy a new CD/DVD burner.

If the old unit is still under warranty, exercise the warranty to get a replacement.

Won't even read cd's- autostart fails...


There are two lasers, one for CDs, other for DVDs. Sounds like the CD read (and possibly Write) laser is worn out, or defective. Time for a new drive. DVDs will be fine, because they don't use the other laser at all.
