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.
Now, if no cables are disconnected, and if you can verify nothing is touching the TV or DVD chassis, you can plug in the unit and check if this helped the player to "see" again. Most of the time you can check as is, though on the combo units you're going to have to slide the chassis assembly all the way back into the cabinet to get it to work because the cables are often too short. If this didn’t fix the problem, please read on.
Other things to check 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.

    Also, in a DVD/CD player there are many complaints where the disc gets stuck inside of the unit. This could be as described earlier, but there’s also what’s called a drawer/disc tray opener and closer mechanism to contend with. On many models, old and new alike, there’s a small belt that goes bad and wont let the tray open. You can usually put your ear very close to the front of the unit and, if this is happening, hear the motor spinning when you press the eject button. Another cause is the nylon gears, which can get jammed up with dirt and dust. Also, in other cases, you could have a motor problem, or the driver IC could be at fault. If you suspect that the motor is at fault, simply measure the voltage on the tray motor while pressing on the eject button. If the voltage comes up between 6 to 12 volts, depending on the manufacturer, then the motor needs to be replaced.

    Alignments

    If you continue to have problems after cleaning and checking the



    GA_googleFillSlot("TL-IMU-Article");




    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.

    Wrapping it up
    If you tried to clean the lens, make sure the unit was trying to spin, and verified the slider is working, there’s not a lot more that a consumer or end user can do. It’s going to be up to you to assess the value of the unit, and compare it to the cost of a new one or the estimated cost of the repair. Hopefully you'll be able to make a better decision based on your findings. If you did make any improvements to the unit and fixed a problem, GOOD FOR YOU!

    As a final step, you must follow the directions in reverse for the assembly of the combo unit. Please remember to tie up any cables or wires that you took loose. Garbage bag ties do the job nicely, BUT if they're the metal, paper wrapped types, keep them away from the HI Voltage lead and circuit board parts inside the set. Remember to remove the wood block if you used one, and please be careful not to hit the picture tube neck when reinstalling the back of the set. Don't forget to put all the correct screws and fasteners in the correct place, as they are put there for a reason!.

    Most importantly, always remember safety when working on anything electronic or mechanical

If you already tried different disc and still wont read it, there's already a problem with the lens of the player and that will need a replacement already , better take it to a service center near you and let them replace it...

Hope that helps.........

No DVD is playing and says disc error all times. The same DVD plays on my computer. I have tried many DVDs and the same error everytime


Hello,

how long have you been using this player? The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load DVD's. The weak lens is also what's making it say disc error.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all DVD's with no problem at all.

Good luck.

When I put on my DVD player, it says "hello, DVD, LOAD, PROT" and turns off...


I assume "PROT" means some sort of protection mode. I would check to see if any of your speaker wires are crossed at the speakers or the receiver. If not you may have shorted something internal.

My samsung HT TQ22 dvd player doesn't play dvd's."DISC ERROR" appears each time I try to watch a movie. Any info on how to fix this problem would be greatly appreciated.


Take the top case off the unit, power on, and place a dvd into disc tray. Press the play button and see what happens. It should find the dvd, clamp it in the reader and then spin it at high speed. If it does this and still says disc error, then the read head is bad. If it does not spin at high speed, then the epindle motor is bad. This is the more common error with Samsungs. Repair shop time.

Dvd player reads no disc and than shows loading


Have you tried other DVD's...you might have a bad one.

If so,,,you may need to clean the laser diode. You'll need cottonless swabs (no lint swabs) and Isopropyl alcohol 99%.

Might be hard to get to, depending on the model, but gently swab the diode lens. Don't saturate it tho.

good luck

Dvd do not loads


Our started doing the same thing about a week after the warranty ran out. It has to do with the alignment of the discs being loaded. here's a work-around that works for us:
Open the tray
Choose which disc you are going to watch and use the Change Disc button to push the selected disc to the back (ie, if you want to view Disc 1, discs 3 and 4 will be visible in the tray).
Look down the center holes of discs 3 and 4... manually move your tray left-or-right to align the holes with the tray.
Push the Direct Play button on the top right of the unit for your disc of choice (Disc 1 using the example above).

hope that helps... I've searched for a while and played around with the unit (with and without the cover on) trying to figure out a way to re-align the tray, but no luck.

Used lens laser lens cleaner & now player won't play.


You can open the dvd and try to clean it manualy.open the dvd so you can see the lazer.take a normal earbud and wet it with normal methylated spirits and clean the lazer gently with that.the lazer cleaners hardly ever work 100%.Just remember not to push to hard on the lazer or you will brake it.gently clean and wait for lazer to dry and try again.
