Question about NAD T760

1 Answer

I have two speakers that cut out often...It seems as thought the outlets fot the center and the back left speakers have a problem. I have tested the amp outlets by pluging other speakers into the outlets and they still don't work. What I dont understand is that when Im done doing these tests and I just give up thinking that I will need to get a new amp...the two speakers start to work! These two speakers had been working for about a week and now they have cut out again. What's more anoying is that there is a constant high pitch noise that come out of the speakers when there not working. I brought the amp to get repaired about 6 months ago and it worked fine for about 4-5 months...now it's back to doing what it did before. My amp is a NAD T760. Please let me know if there is anything you think can fix this problem. Thank you.

Yamaha rx 530 center channel cuts out


Thanks for all the suggestions guys.

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.

Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.

So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?

Thanks

Yamaha RX-V793 receiver shuts down when I turn up volume. Checked the speaker wires and they seem okay. I then hooked it up to an older DVD player I had and it works fine. Don't know if it's 5.1 bu


My first thought would be that when you moved the receiver to connect another DVD, the problem quit since the speaker wires moved. The best way to test would be to re connect the original unit the same way as the new unit and test again. If it still cuts out, disconnect the speaker wires and re test. if it still cuts out, try the new player and test again. if it does not cut out, there may be a problem with the old units audio output. Generally if its a problem with the receiver it would not matter what source you are using, even the tuner on the receiver, if there was a short in the receiver it would cut out. Let me know what your results are and I will help more if needed. Best of luck!

Where can I get a speaker connector?


After a few hours of looking on line and finding nothing I decided to make my own Sharp Receiver connectors. Here are the steps that I took:


_1349.jpgItems I used were wire strippers, wire snips, a file and a sugar free Rockstar (not pictured items: computer power supply, fine grit sandpaper and zip-ties).


_1350.jpg The first this I did was find the 4 pin connector and the 20 pin connector (some times a 16 pin) on the pc power supply and i cut the wires so that there was about 10" to 12" of wire hanging from each connector. These are the 2 connectors need from the power supply to use in your Sharp Receiver.


_1351.jpg This is the smaller of the 2 connectors (the 4 pin) and nothing needs to be done with this one. It fits perfectly into the back of the Sharp Receiver into the area labeled " surround sound". I would just zip tie the wires 3" from the connector and then 6" from the connector.


_1352.jpg The large connector I cut from the pc power supply is the one where all the work needs to be done. The Sharp Receiver requires an 8 pin connector for the are labeled "front speakers/center speakers/sub woofer". Notice the location of the clip for this connector and that it is centered, we need this clip to remain in the center when we are done so re are going to have to remove every thing from it except for the center 8 pins.


_1353.jpg What I did to get the connector to look like this picture is I cut the 6 pins off on both ends of the connector (you would only cut the 4 pins off both end if you are using a 16 pin connector from the power supply). after I cut those pins off I just pulled the wires out from the back side (they come out very easy after you cut the pins off). Now we need to get rid of the extra plastic where we cut the pins. Please view the next 2 pictures before you begin to do your cut.


_1354.jpg
_1355.jpg Notice how I left the plastic intact surrounding the 8 remaining pins we are using. I know that it seems like common sense to do it this way but there's people out there who would have cut the plastic so the pins we need are showing. There may be some jagged edged now from where u cut the extra plastic so to get rid of that we are going to use a file or a grinder. Don't grind the sides completely down though, I left a little bit of the ridges because the new ends have thin plastic walls and if you leave a little of the ridges, it will make it a little stronger.


_1356.jpg I tried to put my, now 8 pin, connector in the back of my Sharp Receiver and it was really snug. This is where the fine grit sandpaper comes in handy. just go around each of the 8 pins with the sandpaper, not a lot, just enough so the pins slide into the plug easy and doesn't wiggle. I used 2 zip-ties on this connector also to secure the wired a little more. Again, 3" and 6" from the connector. Now its ready to be plugged into the area labeled "front speakers/center speakers/sub woofer".


_1357.jpg This is what it should look like when you are all done making the speaker connectors for your Sharp Receiver. All that's left is to connect your speaker wires to your speaker connectors and then all of your components.
I only found 1 website that had the parts for this unit for sale and it was about $50 plus shipping for the connectors. You can get the computer power supply from your local area on www.craigslist.org for $5 or $10, you might have one lying around. If you have any questions or need additional help with this please feel free to email me: jlusk80 @ gmail.com
Thanks for reading my solution!

Yamaha RX-V365 Receiver when I hook up my center channel it is not audible at all. The R and L speakers work fine when they were located in the FRONT A and FRONT B terminals, but when I moved everything to...


With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

Receiver is shutting down.....


First, I have to compliment you on a thorough and comprehensive problem description and an apparent sense of how to troubleshoot. We're halfway there already.

Your Blu-Ray / PS 3 statement is intriguing but with the E-1 code that absolves it as the problem.

You have two opposing symptoms: the live failure says you have a short while the test mode implies an open circuit. We have to isolate everything and see if it moves to another channel.

Let's run with the "E-1: NO FRONT SP" error. I think it's trying to tell us we have an intermittent sensation of an open wire in one of the Front speaker channels. * Unfortunately, the manual doesn't break out Left and Right (but I'm sure the receiver knows) to help us isolate. You say it doesn't get past the Left test. I need you to decide by listening to the Left Front Speaker setup routine if it's really working or not, and if it seems to be working, maybe the receiver is really failing at the point it advances to the Right Speaker, assuming Right follows left in the sequence.

Verify for me: You swapped the two front speakers Left to Right and replaced both speaker wires with NEW wires and had no improvement.

I'm wary of a failcode that doesn't identify which of a pair is failing, so I 'd like to see ALL NEW speaker hardware and connections in place to avoid the pitfall of swapping the L & R with each other and having one of them be the problem without changing the symptom.

We can accomplish this easily: Try temporarily running the rear speakers as the Fronts just to see if the test can pass. If so, test the Fronts as if they're the Rears speakers. You should be able to just swing the receiver-ends of the cables among the speaker posts.

Something should change or else the problem is internal to the receiver. Good luck.

5.1 Surround Sound Cutting Out


HI,
Yes you are right man, this problem occurs only with the cable problem, i can explain you, if there is a receiver problem means you won't get the sound its dam sure,
only if there is a cable problem you will get some noise or sound cut off with the speakers, so you please check the cables properly it will be alright.

No Sound From My Center Speaker


on the yamaha amps you can do a speaker test to see if all the channels are working. once that is complete and working you should check the disc to see if it is true digital or dolby pro-logic. normally on the disc menu you can select this.

Sound cuts out for long periods of time


I have had the same problem. Only differance is that I run a freeview box though my 940 mw. I thought it was that playing up. Also I all the keys are locked on the unit itself. The remote works everything but when I press any buttons on the monitor you get a 'keys locked info' up on screen. Its doing my head in!!!
