I just got a Nad 712 off ebay. Upon initial setup, after plugging in and turing the receiver / preamp front power button to put it in standby mode, the led faintly shows a flashing mute indicator.
Once turned on, the mute indicator turns off, but the led is faint and there is no output from the stereo.
Is there a system reset for this unit? Is there a way to turn off mute without a remote? What is wrong? Should I claim DOA and try to get a refund?

Could be DC voltage on the speaker output line, but this will generally keep your receiver audio output turned off completely. Could be a bad muting transistor or microprocessor IC(computer within your NAD). If you are interested in having your NAD repaired, please visit my website at audioserviceclinic.com.You may contact me there. Thank you..
The contacts in the A B speaker selector switch had degraded on my NAD 7130 receiver. Distortion and signal loss would come and go. Contact cleaner and wriggling the swx knob became useless. Then, years ago I jumped the swx with small lengths of bare wire and tinned the whole thing with solder. Never had a problem since and it probably improved the receiver because it eliminated a component in the output stage that could (and did) introduce distortion.
Solved the recognition of DTS signal issue but the DTS options/settings in the menus are still not appearing - believe the previous owner may have upgraded the software. The solution for the DTS signal recognition was an output setting on the DVD (blu-ray) player - digital output vs analog.
A 712 is not set up to use an Ipod USB dock. You can buy a dock that will use RCA jacks into an old stereo - Apple sells them, others too. Then the Ipod sits up and you can look at it. Or you can buy the 1/8" stereo plug to two RCA plugs that Radio Shack has been selling for 30-40 years, plug one end into your Ipod headphone jack, and run the two RCA plugs into your Aux input. That costs about $5, and is easy as pie. An Ipod will play through any old receiver, but the USB docks will not plug into them.
On my system the bulbs burned out some time ago. Today, I bought a pair of 12v micro lamps at Radio Shack (part 272-1092). Then removed the board behind the display and replaced the bulbs. This required some soldering. The bulbs have held up for more than 6 hours, so I do not think they are going to burn out.
You should connect the RCA connectors from your turntable into the phono input of the preamp. Also, make sure you have the grounding wire from the TT connected to the grounding on the preamp (if you do not have a grounding point, then just connect it to one of the screws on the preamp). Then connect the output from the preamp to either the Tape or the CD points on the T760. On the front panel press tape monitor and you're done.
Check and let me know how it goes. My set up's working fine except for clarity, which still needs to be perfected. I'm using a normal step-up phono stage.
