Question about Samsung LN32A540 32 in. LCD HDTV

1 Answer

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?

Hi!

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!

I have just bought a PRX612M. When I play my digital piano through it at low volume there is a buzz which is most noticable as the notes volume dies down. Loud it sounds great but i would love to know what...


1000 Watts? Well, those are peak values. !000 watts RMS into a 12 inch speaker and it would smoke... this is some of our inflated advertising. But that is beside rhe point... now on to your problem: What you are having is a ground loop. You may have to do more than one thing to correct this here is the things to do in the order to do them to solve the problem:

1. Connect the piano and the speaker to the SAME power source or receptacle, even if you have to run an extension cord, three wire of course. Plug all of this ONLY into a grounded outlet, if your house has only two wire plugs, then you need to get an electrician to install a grounded receptacle.

2. Use Balanced lines. This means XLR or TRS balanced cables between the piano and the speaker. Use the 1/4 inch jacks output, not the RCA ones.

3. Since the AUX outputs do not support balanced lines, the next step require you use DI box. They are about $20 from Guitar Center and others. With very short 1/4 inch mono cable connect the piano to the DI box from the L/R mono piano to the high impedance input port of the DI and set the ground lift switch to "LIFT". Use an XLR to XLR cable from the DI box to the speaker. This last step if needed is the last thing in our bag of tricks to break the ground loop that can cause the buzz. Dirty power, if you have lamp dimmers can be a source of the noise.

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

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.

Loud Buzzing Sound


This may be a power supply failure, and or a short in the output stage, and in the drivers for the output stage.

This is not a repair you can do at home unless you have a lot of experience in troubshooting and analysing problems in power amplifier equipment.

Buzzing after 1 hour


Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
