Question about Samsung LN32A540 32 in. LCD HDTV

Rca l26wd14 buzzing

I have a loud buzzing sound through the speakers when the volume is down .when using the picture modes it is more noticeable expect vibrant mode. itdoes it in every input I have the same issue. Last week I picked up a 32" Samsung LCD from costco. I've just used it for couple of days since I was travelling. For some reason sometimes the tv speakers are making this very annoying loud buzzing sound like something inside the tv is vibrating. I ensured that its not the tv stand or anything that is causing resonance with other external objects. Its inside the tv, like when the speakers are blown up or something, I can swear that this issue wasn't there yesterday. I started noticing it this morning and its happening very often is very noticable - not something that i could ignore. I tried switching channels, changing sound settings etc but it still happens intermitently. Ofcourse I could take the tv back to costco but I heard they are discontinuing the 32" tvs to promote the 37" ones. I really want to keep this since I dont have a budget for the 37" yet. Anybody else running into the same issue or know if this is a common problem with samsung.

    Hey, appreciate your reply. I called up costco and they have scheduled a samsung service guy to come in and take a look. Would you consider this issue something minor? What do you suggest? Should I just take this tv into costco and ask for a replacement or let the samsung guy try to fix it up for me?

I have seen this before in a lcd tv I worked on! My problem was some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). But also check the signal board (rca s-video etc... inputs). My thought in this was a bad cap was producing a harmonic, causing the speakers to squeal! Good luck, I hope this is helpful!

Perform some basic troubleshooting steps that apply to all TVs. These include checking the "Mute" button to see if it has been pressed, examining the L/R balance to ensure sound is coming from both speakers and checking the cable connections to auxiliary components such as the stereo system (which controls external speakers).

Double-check the audio output jacks if you are using an S-video connection (a single round perforated jack) or component video connection (a trio of green, blue and red jacks). Those jacks only run the video signal to the RCA TV. In order to get an audio signal, you'll need to connect red and white RCA cables to their respective jacks on the TV.

    3 Check the back of the TV for a switch labeled "Int/Ext." It controls the sound input on some RCA TVs. If you don't have any separate speakers, the switch should be set to "Int."

    Activate the sound set-up feature by pushing the "Menu" button and scrolling to the sound bar. (This option can usually be found only on RCA flat-screen and projection screen TVs.) The sound bar allows you to set the sound from mono to stereo, activate the surround sound features, adjust the sound for headphone use, set volume levels and activate preset sound levels for movies, sports, concerts, video games and other specific sorts of programming. If any of these settings don't match the configuration of your home theater system, it may cause problems with the sound. If you're confused about the options, select any settings that read "Normal" or "Automatic." That should set the RCA TV to factory standard audio settings.

    Press the "Menu" button and scroll to the "Set-Up" option, then go to "Preferences." You'll see a bar on the menu marked "Maximum Volume." You can use that to limit how loud the TV can get, which can cause problems if you don't know it's been set. Move the arrow on the bar to reset the maximum volume, then hold down the "OK" button on the remote to hear what that volume sounds like. You can then listen to the TV as normal.

    I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum

    Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

    A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

    Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

    Speakers had a buzzing/vibrating noise. had them replaced. still making same noise. happens on very low and loud volume. any idea what it could be? possibly the sound board?

    maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.

    RCA P42WHD33 42 in. No picture and a loud buzz comimg from inside the cabinet not from speakers.

    The buzz is very likely from the power supply. This may be occurring due to a shorted component else where in the units circuitry. The supply has a protect mode when it is over loaded and its operating frequency drops into the audible range when in this state. You will need a technician to diagnose this and give you an estimate, unless it is under warranty or a service plan.

    have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.
