20 Most Recent Aiwa Z-HT65 Shelf System Questions & Answers


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.

BEST REGARDS

Hi,
I have couple of questions,
Does power got ON when power switch pressed and can you load/ eject CD?
I'm in position to help you out technically so let me know can you test volts on specific parts and can do solder work if required?
Waiting your reply to proceed.
Thanks.

Probably something else.
The buzzing is typical of an open circuit input "receiving" radiated 50/60 Hz from nearby mains wiring.
An alternative source of buzzing is the 50/60 Hz mains breaking through into the audio due to failed smoothing and filtering in the power supply.

Capacitors that have been unused for quite a while can lose condition and fail when put into use again and this might have been the cause of the thump/thud/boom you noted.

I doubt it is the cause but it is very unwise to operate an amplifier without a full complement of speakers unless the volume is kept at minimum...

The tape player portion is defective, though new. Many of the site moderators have had that experience.

You would have to open the unit and check for signal right before headphone plug.

It work as a simple twist action. That small, dark plastic part right in the centre will turn, possible with a small flathead screwdriver.

There's no clear all settings there. You need to manually delete each saved station. Try to unplug the power of the unit for few hours and check if that clears all.
