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;

SOURCE: My Aiwa NSX-999mkII keeps switching off

Without speakers indicates that it is shutting off due to thermal protection. Do not store anything on top of it, especially any device that has heat of it's own and give it plenty of air space all around it, at least 6 inches.

I have AIWA NSX-RV85. The sub-woofer surround tore leaving just the cone. When I play, The woofer just makes a rattling sound coming out of vibrating cone.Any advise on how to fix my speakers.Thanks


Refit the rubber, you can find itbon eBay, its called reconing actually in this case the cone is the inlybpart wich you dont want to replace... The rattling is beingproducer due to the fact the rubber normally holds the cone ibto positionering over the coils. This rattling is not good can defect your cone. So dont play it roll you got a new rubber fitted!

I want to play my music from my itouch on my Aiwa NSX-TR77 system (because of the speakers) but do not know how to, or if this is even possible to do so?


It is in fact possible... you can play whatever source to whatever sound system with the correct cable... you need a cable with at one end a headphone output connector (compatible with your Itouch) to an input of your choice on the Aiwa system... usually RCA input (RED & WHITE RCA type connectors) at the other end of the cable...

Cheers!

My Aiwa NSX 990 wont come on. Only timer icon come in display and volumew LED keeps coming on and going off at regular intervals


Unplug the power cable completely to turn off and then turn back on again. Check whether there are no lose parts with missing contact.
Most probably it looks like a deeply digital problem with no do it yourself solutions - bring it to the repairman, but I even doubt he would fix it.
You can also download the Aiwa NSX-990 service manual and analyze more specifically your case. Download it from here: http://www.mediafire.com/?jc0ynzoiama or from here: http://www.4shared.com/document/rQ67hcpG/Aiwa_XG-990-NSX-990-NSX-992.html (click "Download Now", not any other button).

Aiwa NSX-V70 will not recognize that a CD is present. 3 disk tray rotates, CD disk is "picked up" when selected, but the system does not read the CD.


Hi there. Found your post as I was looking for an answer to the same issue with my NSX v70 about an hour ago. I'm pleased to say that I found a solution on the web and mine is now working fine!

Try this address below and follow the instructions. The knob you need is black, with some white numbers on and can be seen from the back of the unit once you have removed the black casing and the silver back. Quite easy when you know how! Good luck.
