Top 20 Nakamichi AV-7 Receiver Questions & Answers

If the receiver doesn't have a function specifically named PHONO, yes. Very few AVR's have phono preamps. They're not expensive. I'd check eBay.

This could be a number of things and withouit taking measurements internally, there is no way to be sure. Some possibilities include:
1) defective capacitors in the power supply.
2) shorted outputs
3) Open power transformer (either the standby transformer or main one)

To attempt to narrow down the possibilities, listen carefully when yyou attempt to power it on. Do you hear a click? Are there any lights on the unit at all? If the standby circuit is OK, you should see the standby light on.

Please update this with any additional details you can and we'll continue from there.

Thanks,

Hi,
I need to know bit details on cd eject problem,

1- Do you see Eject / Open in front display of unit when you press Play button?
If yes then it seems malfunction of Key Buttons on player. Use remote of unit to playback cd and check.

2- Does cd player ejects cd after few seconds try to read it and display shows No Disc / Can not read disc error message? If thats the case, it looks cd optical lens is either dirty (requires cleaning) or worn out and requires replacement.

Above info are for Nakamichi cd player and if model and brand is different, let me know.
Thanks.

its not the fuse problem its the definate problem of ic on the circuit board that has blown out which controls tjhe power on the board to the unit.the number of IC IS -- IC379JC that has to be replaced.also check out the resistor that supplys the power between the capacitor C31011 and IC 379JC.that is resistor number R93 and R94.the cost of the replacing part is not more then $10.but get it replaced and checked fromn a professional repair person in a repair center.it will work after that.
thanks.

You are charging me to tell me how to fix it right?
And you want me to tell you how did I fix it for free? I Don't think so.
Bye...........

Hi,

Based on your post, the pre-amp is doing its job. What might be the mismatch would be the powered speaker system plugged into the output of the Rotel. Depending on what the "powered speaker system" is, it might be that it is a low impedance such as those used in computers whereas the Rotel requires high impedance to be connected to its output. What could be tried is to connect a regular amp or receiver to the Rotel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

in this case the centre speakers are the main route to the sound. 5.1 is for movies, where the centre speaer takes predcedence.

This may sound silly, but make sure that the tape monitor switch is not turned on. If it is not, let me know and we'll look elsewhere.

If you're certain there is no sound going out of the TT...

Setting the Pre-amp Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The Pre-amp Selector Switch
is located under the turntable platter, in the rear-center
(Fig. 1). If the system amplifier you are using has a PHONO
input, set the Pre-amp Selector Switch to the “OFF”
position. If your amplifier does not have a PHONO input,
set the Pre-amp Selector Switch to the “ON” position and
connect the turntable’s output cables to the AUX or other
high-level input on the amplifier (described later).

Turntable operates, but no sound at all
1. The stylus guard is still in place.
2. The tone arm Lift button is pressed in.
3. Amplifier controls set incorrectly: wrong input selected,
tape monitor on, speakers switched off, etc.
4. Check the stylus on phono cartridge for correct placement.
Refer to the instructions for replacing the stylus
on page 5.
Turntable operates, but no sound, or sound not loud
enough
1. If the turntable is connected to an AUX (high-level)
input: The Pre-amp Selector Switch may be set to the
“OFF” position (phono-input level).
2. The input gain of the amplified speaker or similar
device may be too low.
3. The stylus assembly may not be fully seated in the
cartridge body.

You could also isolate the problem to either the TT or the PC by trying the TT on some other sound device like a receiver. Make sure the PreAmp Selector switch is ON and plug the TT into any AUX, CD or TAPE input.

Nice Receiver!
>In your surround sound settings make sure the levels are set correctly and the distance from your listing point to the furtherest
speakers are set to accommodate the levels etc.
>How many speakers 5.1, 6.1, or 7.1 (1meaning subwoofer)
>Pro-Logic supports 5.1 but not sure about 6 or 7
>Pro-Logic II does support all
>Make sure you are hear the sound from all sometimes the sound is really faint if you are in surround mode

Thank You and good luck

HI
>check the settings on the stereo and see if you have the correct setup: AV 1 ( DTS, Auto, Analog)
If you are using the standard RCA cable (red/White) = Analog
or try the Auto if you are not sure.

I hope this can help
Thanks

It definitely has to go through a preamp (a PHONO preamp that is...) something like this: http://www.phonopreamps.com/tc400pp.html

Hello, to set the clock on your nakamichi iPa53DK model click settings the go to general there it will display the date and time. There you can set your time zone, date and time. Then enable the option for set automatically.

To switch off the alarm on the Nakamichi NM-CR-C90, you can follow these steps:

Locate the "Alarm" button on the top panel of the device.
Press and hold the "Alarm" button for a few seconds until the alarm time display begins to flash.
While the display is flashing, press the "Alarm" button again to turn off the alarm.
The alarm time display should stop flashing and return to the current time.
If the above steps do not work, consult the user manual for further instructions or contact the manufacturer's customer support for assistance.

El deck Nakamichi 680ZX tiene la capacidad de grabar tanto a la velocidad est?ndar de 4,76 cm/s como a la velocidad media de 2,4 cm/s. La grabaci?n a la velocidad m?s baja permite grabar frecuencias m?s altas de hasta 15 kHz, que es m?s alto de lo que se puede lograr con la grabaci?n a velocidad est?ndar. Adem?s, el 680ZX cuenta con una funci?n de memoria de m?sica de acceso aleatorio (RAMM) que permite la b?squeda de pistas, as? como la funcionalidad de entrada y revisi?n. Tambi?n tiene un sistema de calibraci?n de nivel manual y un sistema de alineaci?n autom?tica de azimut para garantizar un registro preciso.

The age of this unit and the way it is working lead me to believe the issue is with a component called a capacitor. These components age and fail causing the condition that you are describing. The capacitors are usually in the power supply board and when they fail there is too much ripple current allowed into the main board and the power switch wont latch to turn on the unit. There could also be a bad super capacitor in the main board that functions like a battery and it may have died. Unless you have soldering skills and the right test gear, there is not a lot that you can do yourself.

it needs repair take it to a shop and get it fixed if no fuses seen there is nothing you can do lacking tools, meters and skills.

check ebay

No one uses universal remote these days. They are so 1980. You buy a replacement remote for the Nakamichi. make model replacement remote https://www.google.com/search?q=nakamichi+dvd+player+replacement+remote Send your 230E back to China, it is probably DOA. https://www.google.com/search?q=Universal+230E+remote ..
