Question about Audio Players & Recorders

1 Answer

CD can't be recognized & tape deck clicks - door can't be opened (SOLVED!)

CD's are not recognized. It might spin up and than it gives up and drops the CD on the rotary table and goes to the next CD.

Tape deck #1 clicks several times during power up and stops, Door can not be opened. This is a new problem.

I solved both problems.

    I posted this and solved the problem. This is a Aiwa CX-NV8000U 3-Disk CD, 2-Tape Deck, AM/FM radio surround sound, Karaoke Audio Shelf system. If you read the Aiwa problems the CD and Tape issue are not uncommon, especially the CD not being recognized. I SOLVED the issue thanks to one solution on FixYa and one I came up with my self.

    PROBLEM #1 (SOLUTION) CD issue - It was suggest that you can adjust the POT (a small round rotary potentiometer, like a volume control). The POT is small and behind the optical sensor on a circuit board. It will take a long skinny screw driver to get to it. First remove the metal cover. The POT is black top (the part that rotates) and the base was gray, where three legs come out and solder to the board. You will also see a 'yellow' paint stripe showing it was set at the factory for quality control (ha-ha QC?). Sticking the screw driver past one of the slots in the rear grille, being careful not to hit anything, I was able to get to the slot on the top of the POT and turn it. I turned it clock-wise (as you're looking at the rear of the unit) just a tad, may be 1/30th of a turn. I could see I broke the yellow paint mark. I tried a CD and same problem. I went back counter clock-wise to the original setting & further clock-wise a tad further (one 20th or 30th of a turn). Success. It is working well. CAUTION! You will have to have it powered up with the metal cover off to test the CD between pot adjustments. My idea was to turn one way a small back, than back the other, widening above and below the original setting. In my case it only took two tries. Don't go crazy, its very sensitive and took very little to gain the needed tweak to get it to work again.

    NOTE: I had suspected a failed Laser as possible. I found PARTS ARE AVAILABLE FOR THIS MODEL. The part was about $40 but fortunately the POT adjust worked. Not sure if I'd spend $40 in parts to fix it, but despite all the Aiwa issues its way better quality and features than some of the overpriced garbage out there now. I listened to a bunch in the under $200 range and they sounded terrible. I just spent $25 on a iPod A/V dock with remote to upgrade my mini Aiwa system.

    Problem #2 (SOLUTION) Tape Deck clicking, door will not open, tape deck does not work - There are several long skinny belts. It was suggested they be replaced. Again PARTS ARE AVAILABLE and belts are about $3-$4 each. There are three of them. ALL ARE AVAIABLE. I JUST CLEANED IT. I rotated the wheel by hand with a cotton swab lightly moist with alcohol (not sopping wet, just moist, squeeze out the extra) I cleaned the belts and groves in wheels/pulleys. By the way rotating the large wheel will lower head and free the door. Cleaning the wheels and belts fixed it. For some reason the Aiwa is a magnet for dust.

    Success! I have had the unit 10 yrs? The CD went out 5 yrs ago and just used the radio, tape and AUX for iPod or TV audio. Wish I would have fixed the CD early. The tape issue just happened last week. Thanks FixYa for the tips. They did work!

    DON'T believe negative comments about it's not worth the effort to fix. In my case it cost me NOTHING! Once I figured out what was wrong it took about 20 min to fix it and about an hour of research. Thanks again FixYa!

    Adjusting the POT on my Aiwa CX-NV8000U worked for me about a year ago but the unit went into storage since, and I expect that through the jiggling around it is out again. I am back to this site and have confidence that am going to be able to fix it again. I also see that the tape player jam can be fixed, and will make that attempt to clean and/or replace the inexpensive belts. Thank you, FixYa Folks, for making this site available!

    Where did you get the parts?

Correction on adjusting POT to fix CD not recognizing CD. As I said I tried turning it Clock Wise (CW) just a small amount. Than tried turning it Counter Clock Wise (CCW) back to original position and past (CCW) a small about. I typo-ed that. Any way make small adjustments +/- from original direction in small steps, iterating back and forth from original position till you get success. If I had a repair manual there might be some way to calibrate it or one direction you always turn so I was hunting around.

How can I open AIWA NSX-A508's tape door?

When the deck is clicking when you first power it up, reach inside and turn the capstans by hand and this should disengage the tape head assembly. The problem is the drive belts are slipping and need to be replaced. The door will not open because the head is engaged.

Sony mhc-2600 tape stuck

The tape has spewed out in the mechanical section preventing the door from opening, some outer doors can be removed by too thumb screws sliding up and out, others are held in by plastic clips, the door may have to be pried open to get the outer door off to remove the tape.

I don't have the manual. I placed a tape in the deck and cannot remove it. Help!!! It has happened before, and suddenly I will be able to remove it, and then it will happen again. I'm not...

pry on the tape deck cover with a thin knife and see if it opens...what happen is that your tape deck eat up the tape with the spindle this is due to the fact that the head and the spindle and the pinch roller is clean these parts trick the deck as if it has in a this by when you open the cover push down the lever at the bottom of the tape rest in the tape deck when you have remove your tape. at the same time press play it will start to spin take a cotton swab dip into alcohol press it on the pinch roller until it is clean also apply it to the head. after cleaning you are good to go your tape will stop stuck until the head and pinch roller gets dirty again. good luck.

I have a NSX-V70 stereo. Tapes and CD do not work, FM/AM is fine

Your unit needs a little TLC. Let me address the likely problems/solutions:

1) Tape deck stuck - The most common problem here is that the belt has gotten slippery. This has prevented the mechanism from resetting to a known position and that is what prevents the door from opening. Hopefully when you pried it open, nothing bot broken.

2) Both tape drives run from the same motor and use different belts. The same applies to the second deck as the first. The belts are sliping and need to be replaced.

3) The CD lens is probably dirty and needs to be cleaned. The fact that the CD stops and an attempt is made to play it suggests that the optics are working enough to detect the disc. Clean the lens using a cotton swab and alcohol and that should resoplve the CD problem.

If you have not opened up these before, I would not suggest you start without someone around who has. There are 3 belts that need to be chagned for the cassette section to work. Plan on $15-$20 for the belts.

open the cassette holder and use a pen to push down on the carrier. So long as you don't try to use it again it should stop

Loud clicking

Open the cassette deck and use a pen to push down the heads. After this it probably works better to avoid using cassettes in this machine.

Clicking sound in tape deck

All Aiwas  are prone to this problem.  The doors are a real pain and easily give up the ghost.  I have 2, both probmatic in this direction.
I have spoken to others about this problem. Seems no easy fix.
Have you in your case, tried leaving and old tape in the tape part of your  unit . The noise you hear, usually starts when tape unit area doors are about to pack a wobbly. Unless under warrenty, proberly,
not worth getting fixed.    It seems something gets weak in the activation part and get a mind of its own.  Very common after about 3 yrs of ownership.  All the best: jamz
