Edward, your problem could be a simple one or one that will require you to take the unit into a shop to be alighned.  Try first to clean off the laser lens inside the unit witH a damped cotton swab and see if that helps.  If it does not, you may have a problem with the laser being weak, or the tracking and or focus servos may need tweeking or alighned.  Sometimes a tech can bring up the laser intensity but that is only a bandaid fix.  Unfortainatly, alos of units like this need laser pick-up assy's and the cost to repair is about half or better then the the replacement cost of a new unit.  Good mLuck and let us all know how you made out with this unit.

Thanks Larry,i did take cover off the player.but not exactly sure

if the laser is under the tray.Being that my experience is on tv repair

and video cassette repair.What i noticed is a metallic ring under the tray.

Thanks for your quick reply!!Have Merry Christmas and a Safe and Happy New Year,Edward

If it is a single disc player, you should see the disc in the middle where the disc sits on to the platter or turntable. there should be a small lens looking citcular item. that should be the lens right next to the turntable.

Edward,  The rpoblem you describe is usually either a dirty lens (Larry told you how to clean this) or bad optics.  The alternative possibility is that the DVD is not loading completely.  I am not familiar with the V2000 model, but if there is a belt associated with the loading mechanism and the belt slips, the load may not be complete.  This will show up as not being able to read the disk.  Check for this as well.

 

A word of caution though,  when cleaning the lens, DO NOT apply pressure.  The lens assembly is focused using an electromagnet (coils that condust electricity).  The lens assembly is floating on a few small wires.  Too much pressure will break or distort these causing other problems.

When i looked at the loading mechanism it is belt driven.

The belt seemed fairly loose,not sure if it should have some

tension.The one thing i did that i forgot to mention is when i had problem

with loading,i hit open and before it fully opened i hit close.the dvd i tried

finally loaded.Sorry for leaving that out.Thanks for your reply!

Edward

Yeppers that could be important. As you were told, make sure the mechanism is loading all the way. how you can tell when the units open, is that the disc sits all the way onto the platter and the lems tries to foucus up and down. If the lens does not move, most likley the unit is not loading the disc all the way. Never Please, when asking for help, leave anything out!

The best course of action at this time is to replace the loading belt.  It has loosened up enough to prevent the final load lock.  Changing this should resolve the problem.

December 25, 2006 9:07 AM

Being in tv etc. repair i fully understand that when i serviced to

ask what is the nature of problem.Does it turn on ,can you hear sound,is there a pcture.I am sorry that i left that out.Thanks again.Just one more question can you tell me where to get parts for dvd players?

Hello i ordered a belt.I put a dvd in and the dvd player loaded without a problem.but after warnings about copying etc.the disc said to hit menu to go straight to movie to get by previews.when i did it stopped and the same message can not read disc.when i retired from my tv repair business i sold everything except my simpson vom,and i now own a fluke 12 digital meter.When my rear projo.went out i used the fluke to troubleshoot the problem.found bad convergence amps and two resistors burnt.to troubleshoot dvd players i am guessin a scope would be needed.can the belt cause the problem with the dvd not advancing to menu?

Thanks,Edward

My guess is that the loading mechanism is out of time. The loading gears are driven by the same motor as the DVD sled. If it is out of time, the sled won't move. This will allow the index to be read (as you have seen), but will not alow the rest of the disc to be accessed.

Thanks,Dan i guess after i replace belt when it arrives,it will have to realigned at a service center.not sure if it requires adjustment procedure.

Thanks,Edward

Hi Dan,

I, too, have a simular problem (disc not loading) except I don't think it will load anything.  I have cleaned the lens (I think it is the lens).  I do see it spring up and down.  (I assume that means the wires are in place.)  I have also check the belt and it seems to have tension.  (However, I do see two gears.  One pea-size gears infront of the units to the left (front view).  The other is larger (quarter-size) located in the rear on the right side.  Neither seem to move.  I manually moved the larger gear and it appears the lens moved back.  When I tried to load again, the error message was "no disc".  Is this a good indication the belt needs to be replaced?

I do hear the motor running and a few clicks, but then it stops.

Error Message: ...will not dispaly and ...check the disc. 

Thanks so much....  Elise

There should not be any clicking. I would suspect that one of the end sensor switches is bad. This means that the unit never realizes that the optics are in the "home" position. This will prevent the system from reading the disk. Unfortunately, that part is not a "field replacable part" from the view of Samsung. The only "part" is the optical assembly which is relatively costly. Try inserting a CD rather than a DVD. If the CD plays, that is an indication that the laser has lost the ability to generate the proper power for reading DVDs. This will require replacement of the optical assembly.
Keep us updated.

My Dearest Dan,

You are absolutely gifted!  I inserted a CD and it worked.  I suppose this means it is the optical assembly.  May I ask, the cost?

Thank you so much....

Elise

May 15, 2008 6:10 PM

I no longer work with these on a daily basis, so I don't have exact costs, but figure on $75 for the part at a minimum. This comes as an assembly not just the optics.

Sorry about the bad news.
Dan

May 15, 2008 8:56 PM

Dan is about right, last one I replaced for a customer who said cost was no object because it used to beloge to a passed love one was about 90 bucks with the shipping.
