Question about Car Audio & Video
If you have an ohm-meter check those bulbs. If not just replace them, but, before, check fuses (if there're any)

The front end is bad on this reicever. Your going to need special equipment to trouble shoot this problem, as Its all RF. It is most likly not worth repairing as a shop will most likly charge you more then its worth

the lamps i use on all NAD displays(and have done since the early 1990's) last heaps longer.You can get them from RS components in your country. They are a 14v 37ma type, and seem to last. Never had any come back for replacement again. P/N 351-9585. Increasing the ballast resistor where fitted by 25% in valua also helps preserve them

The problem is the ribbon cable,the one connects the face to the main board,if you live in USA you can order it from pacparts.com or sony.com.
For replace it you will need to open the unit and open the face by moving manually the gears,then remove the side screws of the face and remove face,then remove the cd mech. you will see the ribbon connector.Just replaced and put everthing back togheter.

Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.
The connections themselves are fairly simple but it pays to understand what happens in the loop.
In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).
Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.
The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.
EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.
In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast.
Okay, back to the hook-up:
You have to select any available 'tape loop' containing an overrideable analog 2-channel Out and In.
Receiver Tape Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec, Line-In;
Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play , Line-Out.
So, to sum up, you can only use the EQ or any outboard processor for analog stereo sources. If you actually want to use an analog recording deck you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.
