Question about Samsung LN-S4051D 40 in. LCD Television

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.

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.

It sounds like the main board has gone out. The only audio components are the main board, wiring and speakers. Since audio is missing from external speakers as well, that tells you that the main board is at fault. The cost of the board could be from $150.00 to almost $300.00 depending on the version # of your unit and dealer mark up. You can call 1-800-samsung for nearest service center.

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.

This is a inherent problem in the LG 7 series LCD. It is because of poor padding in between the speaker and the bezel along with a very thing back that causes the TV to vibrate at certain frequencies and volumes. LG is aware of this issue and has new speaker brackets and spaces that will fix the issue. You can contact them and explain your situation if they can send a service center out to fix the issue under warranty as it is less than a year old. If you cannot get it covered, it should still be a cheap repair as the parts should only cost around $20 and take less than one hour of labor for a technician familiar with the issue.

Vizio vp50HDTV10A Plasma Vidio and Audio on and off


Odd problem for this model.

If:

* you are certain the popping is coming from the speakers and
* the video and audio come back on after going out (without reset) then

the issue will be with the main board and will need to be replaced.

Call Vizio customer service, they extend warranties sometimes.

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.
