This problem just began a few days ago. I was reading a manual of a similar product, and it said that a power outage or something to that effect (being unplugged while on) could make the microprocessor malfunction. I tried the reset function instructions to see if it would work on my DVD player, but it didn't. I went into the setup of the dvd player, and saw that "DVD video playback" was switched to 'off'. I then tried another DVD but same problem. When I went back to the setup, I found that "DVD video playback' had went back to the 'off' setting. Is there a possible reset function for this DVD player? (I have since lost my user manual and can't find one online, not even at kenwood.ca)
Hi I wish I had better news, but the problem you describe is the same problem that 90% or more of the DVD and for that matter CD players we service come in with. I would say that in about 60% of cases, the problem is dust or other contamination on the laser lense. If you have just done some drywall or other such work in your home, then that is likely the problem. Also, pet hair or other debris can be on the disc when loaded (especially if you have kids), and if it falls off and lands on the lense, that too can cause problems. The other most common things are a bad spin motor, (if you can, put your ear to the unit while it says "LOADING" and you should hear the disc spinning.) If the disc does spin up, and it is not dust, then it is likely a bad laser, and usually, the cost of replacing the laser makes repair not economical. You could try buying a laser cleaning disc, but I find they don't work well, and you should not take the DVD player apart yourself if you are not a tech, as the laser can damage your eyes. My advise would be to call around to local repair shops to find one that has a the lowest bench fee to diagnose the unit, and have it checked. Since it is so difficult to make a living repairing consumer electronics these days, because of the low replacement cost, you may even find a shop that will check the unit free of charge! Good Luck!
Steps.
1. Buy another identical machine at the store.
2. At home replace the bad unit into the box.
3. Plug the new unit and make sure it works.
3. Get back to the store the next day and return the bad unit (which is going to be inside the new box) due malfunction.
4. Get your money back.
That's it.
There must be a sort of mechanical timing to begin with .How does a factory start and test a unit if it has no starting point? I see a series of holes that look like the should be aligned in a given order. What is the given order, ;at the end of assembly each component should be in a spefic place ,What is that place. the problem seems mechanical.Do the easy stuff first,and work up.
I have a Memorex MVDR 2102 which suddenly malfunctioned - disk tray will not stay closed. I am an ex electronic tech so disassembled the dvd recorder, attempted to clean the laser lens with alcohol (possible mistake) - checked for any residual "q-tip" particles/strands of material, closed the unit up and still have the same problem. I tried the "reset" method in the manual i.e. 1) Turn off unit 2) unplug and leave unit unplugged for a minimum of one minute. 3) Plug the dvd player back in. This was supposed to reset the microprocessor (I suppose) but did no good at all. 4) Let the dvd player turned on and set overnight (eliminate any condensation). 5) Still no luck. Disc tray continues to cycle out after inserting a disc. Icon in upper right hand of tv screen indicates open, closed conditions but disc tray keeps opening. Also no loading of discs occurs. 6) This Memorex fiasco cost me $135 at Target....what a rip off. Memorex/Target have a 90 day warranty (expiration date is on receipt) - be sure to read it. I will never buy a Memorex product again or shop at Target (crooks)!!!! Good luck! I tried everything I know - probably damaged dvd player permanently with repeated assembly and disassembly of unit. Will scrap it and just buy a cheap player (instead of play/record) so when it fails I will not be out so much money!.....I thought the $129 price at Target was too good to be true for a dvd player/recorder and it was. DO NOT OPERATE THE DVD PLAYER WITH THE LASER EXPOSED - IT WILL DAMAGE YOUR EYES PERMANENTLY!!! Thanks for your great website! Regards, Jim ([email protected])
I have bought a new lens for a DVD Player. But it needs to be unlocked, before it can be used. I have fixed the lens in the player, but when i started it, there was no laser beam emitted by the laser diode. I want to know what should i adjust to get that lens working properly? I want to unlock the lens. There are 2 presets on the lens, I tried adjusting them, but still it is not emitting the laser beam. Plz help me.
Thanx & Regards.
Clean lens first with isopropyl alcohol..if not working. check the
spindle motor using analog tester. that id between 200 and 100 using X1
I had this same problem with my Apex AD-500W DVD Player. I decided since everyone said the player basically needed to be replaced it wouldn't hurt to go through the buttons on the remote just to try and figure it out......I DID!!!! I turned on my DVD Player, inserted a disc, turned on my tv and then hit the SYSTEM Button right below the power button until the screen said MULTI and the machine started working perfectly. There are 3 settings in that button, PAL which made my screen go crazy, NTSC ( i have no clue) and MULTI(this one made it work)! Hope it also works for all of you!!!
I'm having the same issue. Sounds like it'd be better to just buy a new, better built one. Shame that DVD players don't last longer.

Try the following
when the error is on the screen, press the number 1 key on the remote, this should take you to the fist chapter of your DVD no matter which region it is

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;

I had a similar problem with mine I have just had a technical fault with mine and the only solution i could find was through halfords. If its under warranty they send it off to their supplier AEL to solve. If its no longer under warranty like mine, they send it off at an initial £60 cost which could escalate if the problem is larger.

display shows loading,then unknown disc or disc.dvd tray opens.the unit plays cds and disc cleaners ok.vic
when I put in a dvd it says loading for a long time and then says bad disc,even on brand new dvds.
wE HAVE THE SAME PROBLEM - HAVE DISCONNECTED FROM MAINS FOR TWO DAYS THEN TRIED AGAIN - NO SUCCESS
My MDP-1760 will load and play DVD's but will not load or play CD's. It sounds like it is trying to read the CD but just keeps trying with no result.
I'm having the same problem of the dvd player not reading discs, even brand new ones that work just fine in my computer. I'm trying to see if the company is still in business, it appears they're not - no good phone #'s, no web-site that I can find. Anyone know if they're still around?
Yes I have the same problem
One minute read the disc but then froze while playing it. Â It said ROOT on the DVD player. Â Couldnt get the DVD player to do anything. Had to unplug it. Now it says NO DISC.. Â Havent been able to do anything.
when dic is inserted it says loading then it says the dis cannot be played please check dis even rented dvds or ones i recorded off tv. try clean dic and use recommeded dic
I had a dvd recorder and a dvd player hooked together. "Both" units blink loading. Will not open or function any other way.
