    My Aiwa model no. is CX-N999K, the display looks more like a vacuum tube with mercury deposited inside.

    You are right! there are two displays, both glow very faintly. What could be the cause of this?

Please post the model number. It is not likely the power supply. Depending upon the model, some use a small bulb to "backlight" an LCD. Others use LED displays. Get me the model and I can provide more details on what to look for.

    Stay tuned. More details tomorrow.

    There are two displays for this unit:

    1)The top display (EQ) is part number: 83NF6618010 $34.27

    2)Bottom display (CD) is part number: 83NF6617010 $34.27

    If both displays are weak, the dispalys themselves are not likely to be the problem. If you can solder, try resoldering all of the pins for the displays. You may need to check the power supply. Unfortunately, trying to describe where and what to check in the power supply, is not easy in a forum like this. I would suggest that you take the unit to a Sony authorized service center for the actual repair if the resoldering does not resolve the problem.

    I am not aware of the service manual being available outside of an authorized service center. I'll look up your model and try to provide more details.

The unit has a power supply problem, no user servicable parts inside. Bose uses a thermal fuse built into the power transformer. Take unit apart and check for connection issues first, then look for a possible fuse, if none exist chances are it is in the power transformer, contact Bose for service.

I cannot get multi CD changer to play CD's. Single CD in main unit is OK but no track info etc appears on screen. Also cannot eject cd's in myulti changer.

This seems to be a failure of the micro controller of the unit as it fails to identify as well as display the functions.
You will need to check he connecting cord , check the connectors and the inner voltage to the circuits.

GG  My kids had a PlayStation 2 that did this and so did my AIWA 3 CD player.  The solution for the PlayStation was to remove the cover use alcohol and clean the lens of the laser reader.  They get dust on them and simply cannot read.  The AIWA required replacement of the laser which cost almost as much as the unit and didn't last 6 months.
