Had the same problem I think. When I would load a disc after a few seconds the unit would read no disc. I opened the unit and removed the transport and there is a board under the laser unit, on that board there is an adjustable pot so I plugged the module to the main board and powered the unit up. I adjusted the pot then sat a cd on it until I found a setting that worked. I hope this helps. I am not sure of your ability. Something to remmember is you can only fix it or break it.

First; try blowing into the DVD reader, sometimes it is just a hair. also try a DVD cleaner disc. Check if the drive spins up correctly, and "listen". If it's spnning but having trouble reading you will hear a whizzing sound as it tries different speeds.

My Nad belt drive turntable is running slow any ideas


stretched belt or needs lube, those are the easiest things, with the unit on, remove the disc so you can get to the belt, take it off the motor and see if the RPM's increase a lot, lube the center spindle with a light oil, and check for easy spinning ,, replace the belt, and turn the disc back and forth, if you see slippage or a binding in the belt, ( like a little loop wanting to develop) replace the belt, if the belt seems to be just slipping, clean all the contact points of the b elt with rubbing alcohol

What's probably wrong is that the player's optical assembly isn't working. If the lens is very dirty or the laser power gets too weak, the player doesn't detect the disc. The player has to see the disc is there before it starts spinning. You can try cleaning the lens with a cotton swab and lens cleaning fluid, but if the trouble continues then the pickup should be replaced.

Cd drive display shows "no


Hi,

Your no disc error can be a DIY like the following steps.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.

I've suspect that the lens is filled up with dust. Below is just for your guide.
2.Replace the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
Ifyou already cleaned the lens, and confirmed that the ribbon is good as well as the motor then I've advice you to send it to repair shop because the next step should be done with an expert because it is quite technical diagnosing the fault between the pick-up lens and the main board.

Hope it may help you.
Have a nice day!

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;


DON'T FORGET TO RATE;

Receiver shut down only when using phono preamp


You may want to try putting an attenuater in the line with the RCA's to cut the input signal back just a little bit. So you are not driving the amp so hard with your preamp.
