Question about Aiwa Audio Shelf Systems
I am wondering if my audio channels are blown. The graphic equalizer LED bars indicate sound, but all I get is a 'popping' like noise, regardless of band, station or CD/cassette play. Time for a new tabletop system?
I thought that I had the same problem. I then discovered that when I put 3 CD's in it started up on it's own. If you push the demo button you can see how it's supposed to light up the number of tracks in a square on the right of the display. It wasn't doing that until I put in all 3. Then it started up and I was able to use the disc 1, 2 & 3 buttons to change from 1 CD to the next and I used the Up and Down buttons to change songs and the play button above the tape deck is multi-functional. Hope this helps.

These are the early signs or optical lens assembly failuer. i would start preparing to replace this assembly. the tracking motor and rail are damaged.

SOURCE: Aiwa CX-ZHT63 Display Trouble
I own a NSX-MT960 and the same thing happen , DEAD DISPLAY.
I just happen to be retired Certified Electornic Tech and Held a FCC first class ticket, and own a tv-vcr -stereo repair shop that worked on all brands,
I had to fix alot of items WITHOUT THE HELP of a schematic diagram and got to be pretty good at it,
THIS HAPPENED about 7 or 8 years ago, but it still may help somebody,
THE DISPLAY IS A VACUUM FLOURESCENT and has a low voltage heater circut to heat it up like old vacuum tube, AIWA PUT IN A SURGE CURRENT LIMIT RESISTOR about a 1/2-1 watt unit with LOW OHMS, I FORGET NOW BUT a 1 watt .5 ohm resistor will fix it, OR JUST JUMP IT for a short time to test, but put that thing back in, better to burn out that resistor than the heater circuit in the display.
HOPE THAT HELPS
RETIRED TELEVISION REPAIR ENGINEER THAT TROUBLE SHOT DOWN TO THE COMPONET LEVEL< NO BOARD CHANGER HERE!!
THAT WAS THEN < THIS IS NOW, NOW YOU HAVE TO CHANGE BOARDS DUE TO SMD WAVE SOLDERING , YOU WILL RUIN A PCB WITHOUT TENS OF THOUSANDS OF DOLLARS WORTH OF DESOLDERING EQUIPMENT.
