Right Channel Not Working

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.

    Same issue here! I opened the hood to see if anything was obviously wrong (fuse, etc.?), no luck. Not looking forward to the expediture of bringing it in for service.

    I have the exact same problem with one channel output, but can not see any obvious soldering problem.

    what have the faulty solderings looked like on your receivers?
    loose, cracked, oxidated?

    Could you please provide a picture or a sketch of the solderings to check?

    (The faulty output on my receiver is the front left.)

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.

    i think that you try to inverse your speakers to see if the problem doesn't come to a bad speaker.

    otherwise you have a defficient component in your reciever and you have to go to a specialist to fix it, sorry for the bad new

The left main channel not working. hook any speaker to it and putting my ear close, it has a very low hollow sound, almost a hum. would there be fuses, a reset, or something on each channel or something...


There is no seperate fuse but it seems likely that the left side preamp or the power amp section had opened up a fusible resisitor that could have shut the section.
Now the only way out is to take a voltage or signal test with the right - working- channel as a reference . Please attempt only if you are familiar if not it will end up with further damage as the sections are very delicate. Testing with a signal will confirm the faulty section to narrow down your search.

The left speaker channel on my NAD T761 receiver is very weak. I can hear music coming out, but very soft and cracking... Please help me out!


Try to swap the input connector, Hook up the right to left input and then the left to right input. If the symptoms is still there then you have a faulty output IC on the left channel. This is not DIY and I've advice you to send it to repair shop to isolate the problem. Hope that you have only a dry joints on that area.
Thanks for using fixya.

Hi there .. i have a nad t752 amplifier , i have just got it back from the nad repair shop , they have just reinstalled it , but now the front right speaker is much softer than the left front speaker ,,...


I hate to say this but the repair was not complete. If the sound levels are different with the balance in the middle, then either they missed a problem in one of the pre-amp stages, or they used an incorrect substitution for transistors in one or more stages. This unit should be brought back to complete the repair.

Any additional detail would require that I see the actual unit and poke around inside with test equipment.

if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.

Sound not coming from left side surround sound speaker or my right side front speaker


it is highly likely that you're TV is outputting mono sound, hence the left channel only. check your physical connections to the TV and the balance / channel volume on the television as well.
