Crackling on Samsung AV-R720

by mparter / January 10, 2010 12:13 AM PST

Recently, my AV-R720 AV Receiver has started to produce a crackling/popping noise out of the front-right speaker. It seems to do it most when first turned on but can also do it when changing from one source to another. It's intermittent and last for a couple of minutes and then seems to vanish for a while.

I've seen this reported elsewhere and it seems to get worse over time and there's never been any conclusion or suggestion of the cause and any potential solutions. It's not even two years old yet so I'm not happy it's failing.

Hello MParter:

I have the identical problem in re the crackling/popping that you describe below, but in my case the problem is through my left speaker. I'm planning to ship the unit for repair to Samsung, but thought I might check with you first to see if you've managed the resolve the problem. Is there something more I can try on my own?

Please advise at your convenience.

Regards, WHersch

grizou660,

Unfortunately, I don't have any troubleshooting for this particular symptom. I'd recommend that if you are having this trouble, reach out to the Samsung customer service center. It's possible that your unit may need to be serviced.

Faulty Pulsus Component
by sarwardc / September 4, 2011 9:50 AM PDT

This is apparently a common problem with this unit. It's caused by the PULSUS PS9829B digital audio processor. Before you try to go and replace it yourself, know that it's a 100 pic surface mount IC so it's not a simple repair my any means. Seeing how many people have described this issue, I hope Samsung cares enough about their reputation to repair these units regardless of warranty status.

No Luck
by LSU_MykuL / October 10, 2011 1:33 AM PDT

The dont, i had the same issue followed by it going into protection mode which was also followed by a pop and smoke. Needless to say, its fried. One guess as to what samsung said..."sorry for the inconvenience" and no repair. To repair would cost the same as replacing. Crazy. Just to add, my TV 55UNC7000 also had pixels go out and becuase i didnt hit the minimum, i cant get anything replaced. So my entire set up is flawed. No more investing in Samsung, they simply dont care.

Meet the drop-resistant Moto Z2 Force

The Moto Z2 Force is really thin, with a fast processor and great battery life. It can survive drops without shattering.
