Samsung HT-E6500W, speaker volume cuts off sporadically.

by kevs888 / April 25, 2013 4:48 AM PDT

I don't know if anyone else has experienced this....

I own a Samsung HT-E6500W with Blu-Ray Player System.

I understand that the surround sound doesn't always have voices that come out of the rear speakers because of the way a show may be broadcasted, but there are times when I'm watching tv and the rear speakers' ENTIRE volume will decrease and then completely cut out.

The only way I've been able to get the volume to come back up is to disconnect and then reconnect the wires behind the small speakers.

The speakers to do not move and the wires are seated properly.

And, sometimes, the front center speaker volume drops to pretty much zero. The only way I can get the volume to come back up is to turn the volume up, up, up and then something catches, making everything turn back on.

I've tried chatting with Samsung, but with online chat, they just use type tracks and apologize and send me the same troubleshooting link.

Does anyone have any "real world" experience or advice?

Thanks in advance.

Hi again kevs888,

Sorry to hear you're having problems with your home theater. Could you tell me when this started? Also, could you let me know if it happens across sources: Cable, Blu-ray, etc.? Also, can you cause the problem to occur? For instance, if it happens in one place in a DVD, can you rewind and cause it again? Does the problem ever resolve itself, or do you have to always do this unplug/replug step to get it running normally again?

Still not working.

Hi there,

Thanks for your reply.

This has been a recurring issue for the past 3 months or so. And yes, it happens across all sources--blu-ray dvd, regular dvd, cable tv, USB video.

I cannot purposely cause the problem to occur. It happens on its own. It rarely resolves on its own without me unplugging/replugging the black and red and then in reverse order.

Sometimes when I unplug/replug, the volume goes back to normal. There are other instances where the volume comes back, but it's just lower.

For example, today I was watching a movie via USB. About 3 minutes into the movie, ALL AUDIO drops from the speaker...not just the vocals. EVERYTHING. I have the receiver set to 3D Sound - High. I unplug/replug and everything is back...for about 5 minutes.

I'm a bit frustrated because I was told in a Samsung Support Chat to save my Chat ID because we had discussed getting replacement speaker wires as long as I tried last ditch efforts like unplugging the system from the wall (which I did with no change in result). When I went back into a new chat several days later, I referred back to my chat ID as instructed and that rep said that it'd take too long to retrieve that conversation and suggested I fill out a repair form.

I purchased this system in November 2012. I hope you can understand my frustration and look forward to any advice.

Hi kevs888,

So the volume levels drop to zero, but the unit stays on, right? It doesn't power cycle or anything like that.

I'm sorry to hear that chat was unhelpful. Could you post me the Chat ID code that you got? I'll get my contacts to look it up.

In reply to: Re: Still not working

I appreciate the questions you're asking. You've asked better questions than all my "support" chats combined.

Regarding the volume levels dropping to zero but the unit stays on...that is correct. There has never been any random power cycle or reboot.

I'll have to look for the Chat ID as it was on my work computer. I only have the chat ID for the first conversation, not the second one where the person said that it would take too long to retrieve the first conversation.

Hi kevs888,

OK, this does sound like a repair issue of some kind. I'd still like the chat ID you have so that we can look up the information. If nothing else, I'll be able to reach out to you to get the repair ball rolling.

Hey Kevs888...

I know what you are going through as it just started for me. I have the same exact home theater system with the same exact problem you have...

Did Samsung come back to you with a fix via software / firmware update? Or did they ask you to send the unit to them to be fixed or replaced? Any help you can give me would be greatly appreciated! I hope Samsung took care of you. I hope they will take care of me also...

Djm3647,

Preaching to the choir. Random spontaneous main volume starts decreasing. Try to turn it up with the remote and it's like the machine is battling you to reduce the volume. Called Samsung tech support and after four fruitless calls, I was told my one-year warranty is out despite the fact that the machine is 11 months old. Sent in the receipt as proof. I'm surprised I have to go through this fiasco. They're still "evaluating" my proof of purchase.

Mason7370,

Sorry to hear that Samsung is giving you such a problem. I have yet to call them (been working a lot) but hearing of your fruitless calls to tech support and then them telling you that the machine is out of warranty... Man, I have got sinking feeling. That's too bad. I have usually had excellent experiences with Samsung products, but this machine is making me start to doubt the quality of their products.

At any rate, I will give Samsung a call this weekend and hopefully someone there can come up with a fix. I will come back and post the results of my call; hopefully not fruitless.

Good Luck Mason7370!

Well, they evaluated my receipt and deemed my machine was still in warranty. They sent me a UPS prepaid shipping label and I sent it off this morning. We shall see. The good news is that I didn't have to continue the battle over the warranty.

I would say that I'm nervous that the machine is starting to have problems right as my one-year warranty runs out. I fear they'll fix this and like a month from now I'll have more problems. I recommend you call them right away to get the help ticket going.

From my end, I always ran and installed all the updates on a regular basis. I did nothing to cause the machine to start with the random volume decrease issue. We use the system on a regular basis, pimarily for Netflix and to watch movies off of an external hard drive I have connected to the front USB port. Who knows what made this start to occur? All I know is that for $550, this should not be happening.

Mason7370, I am glad that Samsung finally took care of your unit... Yes, I did call them (to at least start getting something documented) and they had me try things that I had already done. Unfortunately, until I go through all of their protocols and level escalations, they are not going to do much of anything. Like you, it is probably going to take several calls before they realize that something really is wrong.

djm3647,

They researched it and deemed mine still in warranty. I sent it in on a prepaid UPS label and just received word yesterday that they're sending it back repaired. Here is the diagnosis and repair that was conducted on my machine:

Symptom: KEYS/KEYPAD STUCK NOT FUNCTION
Repair Description: PARTS REPLACED-APPEARANCE
Part # AH96-019378; ASSY MISC P-FRONT KITTING(ITO+F);HT-E673

It's being shipped back to me. I hope this repair solved the problem.

Mason7370,

Funny thing... I found that after I messed around with the volume controls on the unit itself and popping open the little cover beneath the controls (the cover that protects the volume calibration microphone jack...) the volume problem has stopped completely! I have not had a problem with it for 5 / 6 days!

I think your problem should be solved. I wonder if there is an issue with the volume control button contacts.

Now, I wonder should I continue to pursue this with Samsung... the unit has not troubled me with the volume and I am okay with leaving the little cover open... But I wonder still if there is a bigger underlying problem. I still have 5 months warranty on it. Maybe I will just keep an eye on it for now. If the problem returns then I will know I have a bigger problem.

At any rate, thanks for posting the Symptom / Diagonsis and Part Number. I am going to save this info and should this issue come up again, I will give Samsung this info.

I hope your unit will not trouble you any longer once you get it back!

thanks!

Solved the problem
by AstroScout / June 11, 2017 5:10 PM PDT
In reply to: Same issue

I had the same problem, and on other forums they suggested removing the board with the valves as they overheat the circuitry. This doesn't affect the sound quality at all. Unfortunately, this didn't work for me, but I found that I could disconnect the front panel volume controls as a permanent fix. The volume control via the remote still works.
To do this, remove the main cover and then remove the front panel, you can then see the wires from the volume control run along the back of the panel and into the display circuit board via a plug. Just unplug the cable.
Note that my symptom was that without touching anything the unit beeped exactly as if I had pressed the down volume button on the front panel, and then the sound volume decreased to 'volumemin" by itself.

Wireless Module included
by Highland_Logan / August 18, 2013 3:08 AM PDT

Have you re-synced the wireless module for the rear speakers? This is part of the trouble shooting procedure for this unit. You may be getting interference from other wireless products in your home.

I know this is an old thread, but others may have the same issues.

Same Problem - Decreasing volume till it hits 0
by MikeCT7 / November 3, 2015 11:09 AM PST

I too have been having this issue for 3 years and I'm still not happy as I've been told the problem is caused by the heat from the valves affecting the volume control.

I wish I had never bought this piece of kit as Samsung are now saying it's out of warranty no and that either I take it in for an engineer to look at it yet again at my expense or forget it, but even if they cannot fix it Samsung will not help me even though it was reported first whilst in warranty.

Fixing the volume dropping to zero
by Pepeuno1 / November 25, 2016 7:49 AM PST

Thank you. I had the same issue for the last 6 months after owning the same unit for 2 1/2 years. Today, I removed the vacuum tubes and so far it has been working after 2 hours of continuous use.

Do you know what these vacuum tubes control?

Is not working...again.
by Pepeuno1 / December 3, 2016 5:39 AM PST

By the way, after one week the volume keeps dropping to zero. I guess that's it. I'll have to replace the system with probably a Sony. No more Samsung.

Touch function problem
by Ashwadkhan / September 3, 2017 12:10 PM PDT

Best way is to disable the touch function completly and use the remote. When you remove the front panel with the display board. Just remove the two flat ribbon cables coming into front touch board. Should work without any problems after that. Also never disconne the valves thats inside. It is for front pre-amp circuit.

REMOVE VACUUM TUBES CIRCUITBOARD ONLY
by Husam-Z / December 26, 2015 12:59 PM PST

The vacuum tubes get too hot and effect the heat activated volume +,- sensors under it

Remove the vacuum tube(s) circuit board only (the small circuit where the vacuum tubes are connected. It should work 100%, same sound quality

Alternate To Removing Circuit Board
by dickhull / April 2, 2016 9:30 PM PDT

Taking the overheating problem suggested above as a clue, I tried mounting an old computer block fan blowing upward beneath the area where the vacuum tubes are located. I cut 4x2" sections of 1 1/4" PVC to elevate the unit so the fan would fit under the 6500. The fan itself was elevated with spacers to be flush with the base of the unit to permit air to flow from underneath the fan (in its final location in the forward corner directly beneath the tubes, the fan became the 4th leg to elevate the 6500, so I ended up needing only 3 of the PVC legs). I powered the fan with a 12v power supply which I may later put on a switch or relay to shut off automatically when the unit is off. I had to experiment with placement of the fan until I found a position that would do the job. In the final location, we watched a full DVD movie plus a couple of recorded programs and the nighly news, about 2.5 hours in all, without the volume going to zero--I may be a bit premature in reporting this, but I felt 2.5 hours was a pretty complete test. This approach is a bit clunky, but I was reluctant to break into the 6500 to remove the vacuum board as suggested above. I intend to spray paint the PVC and block fan with black paint to make them less noticeable.

Even Simpler
by dickhull / April 7, 2016 1:12 PM PDT

So, after setting up my cooling fan and testing it successfully as reported above, my wife, on the following day, did not remember to turn the fan on. The unit still worked all day without cutting off. It turns out that elevating the unit an inch or two to allow more free flow of air apparently provides sufficient cooling. The unit has now worked fine for several days, even when left on continuously for most of the day and evening. I fashioned smaller 'stilts' with some 3/4" pvc, which when painted black are almost unnoticeable, and all continues to work well.

Slightly more elegant solution
by aetherly / November 7, 2016 5:17 PM PST

I am so thankful for this post as I have also implemented the mentioned solution and it is working great. In my case, I purchased a standard cabinet fan that was already powered for $18 from Amazon.com (4.5"x4.5"x1"). Then i purchased a nice looking set of shelf supports (2" high) from Home Depot and implemented the fan solution and it is nice looking and very functional. Take a look at the attached picture. Hope this helps someone out because without this solution, my unit was nearly useless.http://i67.tinypic.com/2wgc2ky.jpg

Samsung should take responibility
by Ozcitizen01 / May 21, 2017 12:57 AM PDT

Same system - same problem - this is clearly a design fault. Mine was fixed under by samsung inside the first 12 months - but again I have an unusable sound system. I bought a Samsung TV - Samsung blueray sound system - TV failed (repaired under warranty) sound system failed. That is a 100% failure rate. Will not touch Samsung again.

Fixed
by Rsubramani333 / July 9, 2017 5:36 AM PDT

Hi guys had the same problem.was fixed quite easily by removing the front panel and removing the short ribbon cable directly going to the touch volume control. This only disables the volume on the front on the unit. All other touch buttons work. I will now only use volume on the remote or via arc port.
