Dear all Hi! I am a electronics engineer and I have Nakamichi 680ZX cassette deck, its FL indicators are not functioning. I had checked for both channels output signals on switch PCB. I had received audio signal on pin # 5 of IC 904 (RC4560D) on Indicator PCB C ***'y, further no signal on pin # 7 but (-)10 Volts DC with respect to ground, of the same IC. I would appreciate if you could guide me to rectify the problem. Please also note that I have complete full service manual for Nakamichi 680ZX. Best Regards Muhammad Ali Shah

I'm not familiar with this product, and there the best I offer is that you consult the user guide (which you probably already have)
http://www.ps2netdrivers.net/manual/nakamichi.ta-4/#manual
or (buy) a service manual (which it seems includes a troubleshooting guide) from any of a number places, two are given below:
http://www.manualszone.com/en/nakamichi-service-manuals/62888-NAKAMICHI-TA4-service-manual.html
and
http://www.nakamichi.owner-manuals.com/TA4-service-manual-NAKAMICHI.html
All three manuals/guides are available from
http://www.hifiengine.com/manual_library/nakamichi/ta-4.shtml
There other websites where you an download the service manual (I don't know if the are the 'official' service manual, or different ones that have been written by different people).
If you are really stuck contact Nakamichi through www.nakamichi.com or (what appears to be a more friendly site) http://www.nakamichi.co.uk/support

Naka 700ZXL- Intermittent Problem: After turning on the deck and at the same time the reel motor turns to eliminate tape slack one or more of the 15 lamps on the RAMM indicator panel turn on. If you...


from what is described of the lamps and the RAMM indicator the the negative 4.5 volt supply and the sometimes double spiked signal sound as though you have a weak regulator component or a voltage control circuit with a bad or weak component that needs replacement.
1. check electrolytic caps
2. all diodes/ resistance > all dropped/ no voltage in the voltage controlled circuit
3. trace voltage and current back to source to see if the supply is correct.\
If this is intermittent it means that a component or several components are growing weak and need replacement
4. a schematic for the unit is very helpful in isolating circuit component failure.

I have a 1999 Lexus LX470 with a Nakamichi audio system with a 6 cd changer in the dash. The cd's will not eject and the screen says error. What can I do about this?


I feel your pain......and did extensive research on the internet.....Google "LX470, CD, err3" or "Nakamichi, CD, err3".

Take a look at this excellent explanation of how to dismantle and remove the head unit and retreive the jammed discs. I have used it and fished out three discs, but the CD Player still shows ERR3. An hour of work, so be prepared.
http://www.celiamania.com/wordpress/?p=135

This is a site that provides repair services once you get the head unit out. http://www.carstereohelp.com/lexus.htm
"Six CD changer, Err message in display, will not play CD's, will not eject or accept CD's. Before repair, disconnect one of the car battery terminals for several minutes. This acts as a reset and may bring the changer back to working conditions. Otherwise, repair rate $385."

The Lexus dealer wants $750 to replace with a refurbished unit. Don't go down that route. Read these nightmare stories.

Don't buy a stray unit off of ebay, it is probably jammed or broken with the ERR3 meesage too!

If the home repair method doesn't work, then it will be better to just upgrade to a new head unit. I am buying a Jensen VM9215HD to get a multimedia system with all the trimmings and full iPod control for $460. Available on ebay or online stores. I'll install the unit myself, but you can get the unit and the job done at a local auto sound store for under $1000.

Good luck,

NO SOUND


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
