NR 1510 sound issues.

[Ravi B.]

Hi all,
I have been using Marantz nr1510 with klipsch reference speakers, for around two years. Lately, I am experiencing a problem of no sound , when I switch on the set. After a couple of power resets it gets going. Tried network reset. No good. However, sound doesn't go dead midway while playing.
Kindly advise.

Network reset because it's using your network when it goes out? A regular factory/microprocessor reset is different and probably worth a try. Maybe even just a soft reset can help (unplug avr from power for a bit).

Hard to know what the issue is for sure. My hunch is the muting circuit is unstable, but there could be a number of causes.

I would do a full reset to factory defaults and reset the receiver up. Preserve your settings prior.

If that does not work there is really nothing else you can do.

Did you buy the unit new? When did you purchase the receiver?

I fear this issue may get worse and lead to failure of the unit.

From my experience, Marantz service is rock bottom at the moment. They are an outfit failing that has been sold to Harmon, but the monopolies commission is investigating to see if the deal should go through.

Wow another anti Marantz rant with little to go on....you'll be a favorite among the fan boys of the brand.

Yes, I've been doing soft reset, and that works after a couple of shots.

What do you mean little to go on!

The fact is that Sound United were bought as a vanity project by the CEO of a medical equipment company Masimo. It has been a disaster and that is putting it mildly. The CEO was voted out by the board.

Sound United have been loosing money hand over fist. That is data that is available and I have reviewed. So they have been bought by Harmon Int. which is a subsidiary of Samsung. The Monopolies commission will take until at least the end of the year to approve the sale. If not approved then who know what will happen as Masimo can not sustain the losses. This is all public record, which you can confirm and not a rant.

My 7705 AVP failed at five years and could not be repaired due to lack of parts and has been recycled.
My 7706 failed at three months. It has been in for warranty repair for two months and I have received no communication from Marantz. I don't think that can be considered in any way acceptable

I did purchase a Marantz AV 10 as options are now very limited for AVPs. This was a risk I felt I had to take. But I certainly hope it will not develop any faults, at least until Sound United has a "safe harbor". If not I fear Sound United will likely disappear or be sold off in parts.

You can call that a rant if you want, but those are verifiable facts. This is something anyone contemplating purchase of a Sound United product should certainly consider.

Didn't even realize this was your post, hope you never figure it out, traitor!

Because you make a lot of assumptions based on little fact. Like the Amazon reviews you seem fond of. Good luck, you still have a questionable unit from a questionable company in your own opinion....

Same guy you mentioned shouldn't be allowed.....maybe review his posting, particularly about the drumph.

ps sure, with enough drumphy crapola could be getting into my cups

Everyone of my statements are verifiable facts.

The only statement that is correct is that I made an expensive choice from a currently questionable company. However the only other options were an Anthem and they really were not ideal for my needs and our leader steered me to the AV 10 and I think his advice was correct. The only other option would have been a hugely expensive unit that really did not meet my needs. So the AV 10 was the least worst option and I hope in the fullness of time it will prove to have been a very good option.

I have to say you are not making any sense tonight.

You still bought from a brand with questionable ownership by your own statements is more what I'm referring to. I still think you're likely suffering audiophilia with your new gear.

No, they are not. You have limited experience with the gear you bought, which was probably no better than avrs with pre-amp capabilities.

 

[lovinthehd]

More reminds me of your idiotic comments about bicycle mechanics whose sophistication far exceeds mere audio design.

I am now totally fed up with you. The AV 10 is a better unit and this has been documented by both Gene and Amir. Just the dead silence of the AV 10 is worth the upgrade. However there is no doubt the the overall sound is improved. There is also the pleasure of the beautiful build quality and craftsmanship. This is on a par with my Quad gear and other first class vintage gear. I am someone who really appreciates well designed and crafted gear, and this AV 10 is in that category. You should also know by now, that I can not drive my system form the preouts of an AVR. That would just not be possible.

I don't know what you problem is, but you are like the "dog chewing the proverbial bone".

I am sorry we have had a disrupter here, which has been a distraction. I apologize on behalf of members here.

Anyhow, when I woke up this morning it came to me what is most likely the problem with your receiver.

It is likely in what is known as the LM timer circuit. This is an ubiquitous circuit built round a Texas instruments LM timer chip. This is a circuit that disconnects the outputs until the circuits stabilize so you you don't get a loud pop through the speakers. The time of the delay is set by the value of some capacitors connected to the chip. These capacitors can fail over time. So I think when you are switching your unit on and off, it is restabilizing the timer capacitors. This is a common way capacitors fail.

So if the problem gets worse and that is likely, then the unit will need service.

Unfortunately these days it is usually by board replacement, as the components are placed by robots these days and surface mounted and not through and through mounting using hot air soldering.

Your unit may operate for a significant period of time as it does now before there is total failure of that circuit and it won't turn on.

Thank you for the detailed response...ominous though it seems....

It could go for a very long time like that.
