Housing Vibration During Certain Frequencies (At Normal Volumes)

I recently had my speakers and main audio board replaced by a Samsung authorized repair center to correct this issue. About a week later, the vibration has returned, mainly noticeable when watching a dvd and only during certain frequencies. My speakers are mounted by what appears to be rubber posts but the speakers are not actually screwed to the housing, they "float" in the housing by design. Would some sort of felt clamshelled between the front and back housing seal correct this? Is this a common problem with LCD TVs? I've heard of the speaker housing itself being wrapped in thin foam?

Any suggestions would be greatly appreciated. I'm not getting anywhere with Samsung or the repair center. I'm under extended warranty, do you suggest I request a refund or exchange?

Thanks.

Dave

    I, too, have the same Samsung LCD TV and audio vibration problems at certain frequencies. It's intermittent and annoying. Has anyone contacted Samsung Corp. directly about this issue?

Me again. I removed the rear plastic housing of my TV a few weeks ago on a hunch that the resonance frequency of the two speakers were matching that of the plastic rear housing. Yep. Once I removed the plastic housing (about 8 screws), all speaker vibrations ceased. It's been fine ever since. However, I don't particularly care to have the back off of it, although I see no high voltage parts like a yoke, etc. sticking out or within reach. It's also not mounted to a wall and is in a position where folks can't easily get there hands into the back. I'd still write to the CEO of Samsung since this is a wider problem that they should address without charging a tech fee.

SOURCE: Housing Vibration During Certain Frequencies (At Normal Volumes)

Sir
The problem very well could be with the DVD player because the disc is spinning very very fast and it might be causing the vibration thru out the chassis. Is this only with DVD ? You mention mainly DVD so I would like to know can you notice what type of scenes are causing it with TV ? Maeaning bright scenes or dark or something else?
Hope this is of some help. If you still can request that they come again as the problem isn't fixed. They might replace instead of coming again.

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

I want to hook two speakers on each terminal (L/R).


The correct way would be to hook only one speaker to the powered outputs and use PRE-OUT outputs to connect separate amplifier (or active speakers).

For 2 speakers to work connected to the same powered output of receiver, their impedance would need to be high enough. Yamaha receivers officially support impedance >= 4 ohm for front speakers. If you would connect 2 different 8 ohm speakers, the combined impedance could be theoreticcaly 4 ohm, but that depends on many parameters. On low volumes it should work, but could overload the receiver if used for louder volumes.

Also note that the impedance is a function of frequency (specific to every speaker), so for different frequencies the power from receiver would be devided differently between the speakers and the sound would not be good.

Sound gets muffled at certain frequencies. Please Help!


I think that rather than the mixer, that your front speakers may have a limiter built into the high frequncey amp. You may be asking them to do more that they are capable of.

Poor sound on my plasma bad speakers


It could be the speakers or the main board. The audio circuit is comprised of the main board, speakers and wiring. That's it. I have seen pinched wires cause problems as well as the other components listed above. You can call 1-800-samsung or go to samsung.com to find the nearest authorized service center.

Sound vibrates


Test it by moving the bass and treble up and down. If the buzzing seems disappear at lower volumes with little bass and appears from one side only, it is probably a blown speaker on that side.

If the buzzing is apparent even at very low volumes or from both sides, it is probably an audio board issue. I am not certain if your model has a separate audio board or that functionality resides on the main board.

Sounds like your speaker is blown . Is it a stereo? If so you can try switching the balance to the other speaker to see if its only in the one speaker. You can also switch it to mono to see if tat makes a difference. Let me know what you discover and I can help you further.
