Question about Durabrand DUR7 Portable DVD Player

Not playing DVD's

My unit comes on and displays the generic DVD Video screen. The DVD's spin. When I test the pick up it centers and the laser comes on seems to try to focus. Still, not reading DVD however. What else is wrong? Help please.

    The display screen comes on and says no DVD when there is a DVD inside. It seems that it is not turning the DVD or not loading the DVD.

    It was purchased in 6-2005 so it is not even two years old.

    Also, when charging the battery, it seems not to be making a connection.

    Just this past summer, I purchased a Durabrand portable DVD player (Model PDV-709) it worked just fine until my 2 year got a hold of it. He manually forced the laser back and forth several times (I imagine) before I caught him! Now when a DVD is played on there it will recognize it briefly but always freezes up or stops completely before the main menu appears. I've tried manually moving the laser (I know not the best thing) toward the center and trying the whole thing again and still nothing! We don't have a warranty and I am hesitant to take it to some Joe Schmoe and get ripped off! Any suggestions?

Coby portable dvd player model tf-dvd1021...load dvd into player, then "wrong disc" comes up and player just stops! Won't play dvd after that.


Check and replace the Laser Pick-up unit of the DVD player. It is weak. Contact any service technician. This work cannot be done by a user. It is somewhat skilled one.

When loading a dvd it displays, "NO DISK". Is it


Hello
There are mainly three motors for most of the DVD players. One to spin the disc we insert in, other to load the laser pickup unit to-and-fro inside it to read the disc and an other one to load the tray mechanism 'in-out'. According to your description, the disc spins inside, and you can hear its spin. So motor which spins the disc has no trouble at all I should say. Then comes to the second motor that moves the laser assembly inside it. If it do not work, the laser pickup unit won't move and no reading will take place and 'No Disc' display will be the result. The last chance is with Laser Pickup Unit itself. Just get this unit repaired by any well experienced service technician or by the authorised service center, because, there are special tools to open this unit. As it is a compactable one, more care should be given to it while repairing. Suspect the second motor I described earlier, and the Laser Pickup Unit. OK.

I have a philip 3962 it can not read DVD but it can read regular audio can you tell me what happend


hi,
i have got the same complaint some days ago. your players spindle motor is faulty.
its winding have some problem. spindle motor is that one on which the dvd spins. when u insert the dvd it is not rotating at the required rpm. thats why it is not reading. the problem will not be with video cds and audio cds . because it doesn't required a high rpm. replace the spindle motor. it will not cost a lot. its sure that ur problem will be solved.
if then also the problem remains,
your player's laser pick up unit have some problem with its DVD laser. there are two types of laser in dvd players. one for reading and playing audio cds, mp3 and video cds and the other for reading and playing dvds. in your player dvd laser have problem. don't think that these are two separate unit. the lasers are mounded in the same unit. if any of the laser get damaged you have to replace the whole unit.
if u need any more assistance feel free to contact me through fixya.

Bush combination DVD/Video problem


Manually cleaning the lens
To locate the laser lens, look around the door or drawer of the DVD player and you will see a small circular disc, which is often called the turntable or disc platter. Right off the edge of the platter you should see a small clear lens. There are some manufacturers that have had problems with the lens, depending on the age of the unit. In these problem players, moving the unit to a different location, turning the unit upside down, or sometimes even without moving the unit, the lens can become detached from the laser assembly and floats around inside the unit. You can re-glue it back with a little crazy glue, BUT it must be perfectly centered, and without getting any glue on it. So, if you don’t see the plastic lens, but instead see the laser pick-up assembly, look around for the lens inside the unit and glue it back on.
To clean the lens you must use very little pressure. Take a cotton swab and barely moisten it with plain, non-scented, or oily type alcohol. In a swirling motion, very gently rub the lens until you’ve covered it entirely. Then repeat using the dry end.
If the cleaning didn’t help, don’t despair just yet. You can see if there’s a problem elsewhere in the unit by using a few simple tricks and tips.
First thing you want to see if the unit’s laser is in good working order. This method isn’t foolproof, but most of the time works admirably. When you insert a disc, see if you can look up underneath where the disc sits on the turntable. Observe the laser lens going up and down. If the lens is trying to focus, that’s good! After a few seconds of the lens trying to focus, the platter should start to spin. On almost every CD/DVD unit I've encountered, the unit won't spin unless the laser has properly focused on the surface of the disc. If the unit spins up and and then shuts down, you should check and make sure the laser pick-up assembly slider mechanism is working without any obstructions and that the small chrome rail that it slides on is slightly greased. Don’t go overboard with the grease though, as too much can cause all sorts of problems.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.

hope this may help;
