Question about NAD T752 Receiver
The RIGHT front channel of my NAD T752 is not working properly. THere is a faint sound coming form the speaker, but that is all. I have run all normal diagnotics (switched speakers multiple times, changed modes, checked connections and re-wired the speaker connections. I have no idea what this may be. It was working fine recently and all of a sudden this. Please help is you can. Thanks.
I have had the front, left and right channels go out over time. I have fixed all of them, and each time it has turned out to be a cold solder joint. While I love NAD and will continue to purchase there equipment, this generation is plagued with poor workmanship.
To fix the channel going out, I removed the top cover. Back cover and 2nd card from the left (looking at the receiver from the back side). This card handles all of the audio processing. I have found cold solder joints all over this board which has caused channels to suddenly go quite. I have never found a bad component. Also, I have cleaned the interconnect to be backplane (board that the audio processing board connects to) in the case of the center channel going quite.
If you have poor FM reception, the first board from the left (looking at the receiver from the back side) may have a cold solder joint on the coaxial connection for the FM antenna.

It's definately a electronical problem in the signal processing part of the reciever. I've had the same problem three times with my T752, on one or more channels.
