Samsung LN40A550 Popping noise

by nodefargs / January 14, 2009 3:06 PM PST

I recently puchased this set from future shop as a package with the Samsung Blu-Ray and 5.1 Theatre in a box set. When I play normal DVDs in the blu-ray and watch cable shows through my Shaw HD box I get a loud random popping noise coming from the LCD panel speakers even though soundtrack and audio sound is not coming through them. It sounds like a static discharge and I'm worried it's damaging the speakers or internal circuits in the LCD display. It sounds like what happens to cheap Computer speakers after years of use. Should I return it? Is this worthy of a return under warranty.

It's incredibly loud much louder then the DVD or Cable audio sound coming through the Samsung Home theater reciever.

Initially I thought I'd solved it due to a loose power cable but it came back and that does not explain why its coming through the speakers.

Any feedback is greatly appreciated.

Thanks for your support of Samsung products. I'm sorry to hear that you're having these issues with your new set.

I would definitely consider getting the unit inspected by a service technician. This is not what I'd consider normal operation.

Keep me posted.

Popping noise recommended solution

I phoned Samsung service today and they suggested I try moving my speakers farther apart. Apparently the Home Theater speaker magnets interfere with the TVs magnets if they are less then 5' apart. This will cause damage eventually to the TV speakers.

Those must be powerful magnets.

My question then is where do I put my center Channel speaker if it needs to be 5' away from the TV? Or is there a way to magnetically shield these speakers? I will try to move my speakers but I have limited space in which to do it.

I will let you know how this goes.

Samsung speaker popping
by pdxcamper / January 27, 2009 8:40 AM PST

I have a similar issue and am looking for some help. I have a Samsung 46" LCD model LN46A630 TV and I get loud popping out of the left tv speaker randomly while watching DVDs or cable TV. However, the sound for the movie/show is not coming out of the TV speakers but rather the stereo speakers and the volume on the TV is set to zero but the popping still occurs. The receiver is a Denon AVR-2809CI and it is connected to the TV via HDMI. Moving the home theater speakers more than 5' away seems unreasonable.

Any help appreciated.

I've found a temporary workaround that does not require moving speakers.The popping noise from the TV speakers are eliminated if you use the mute function. however you are then stuck with the mute icon floating around your screen as you watch movies.

Is there anyway Samsung might update the software to turn off the TV speakers when the AV system is running? Or perhaps just to stop the bouncing mute icon?

Turn off TV speakers?

Can't you just turn off the TV speakers? (Go into the sound menu, select "TV Speaker", and set it to off).

Shielded speakers?

Are your home cinema speakers shielded properly? I read somewhere that some are not and can result in problems if close to the TV (CRTs that is as magnets make "fun" colours with those Happy

I have this exact same problem with the same model. Any word on a solution yet?

I too am having the same problem. I bought the entire Samsung TV/Blue Ray/Amp/speaker system in January.

If their own speakers are not shielded properly it is their fault Happy

I tried moving the L and R speakers away from the tv and the center speaker away as well. This worked for a few days and then the popping came back. The only thing that works is the mute button. (but then you have that floating mute icon)
I've downloaded the latest firmware (1006.1) and still popping...

very annoying to say the least...
