My Samsung TV that i use as a monitor makes a bussing sound

Specs: windows xp sp2, 3.2/2gb
Hi not sure what to do to solve this issue. Seems to be getting worse. If i mute the sound or lover the sound things are still the same. It is a samsung tb/monitor and i use the vga port. I use it with sound from the soundcard which is onboard. Not sure what other info is needed

Your only real option is to have the TV looked at by a trained technician. TVs are not user serviceable.

"Not sure what other info is needed"

Model/model number of the TV would be helpful, system specs would be helpful too. I kinda doubt you're still running XP SP2 (or are you?). Does the TV make the noise all the time, regardless of whether it's connected to a computer, used as a TV, or has nothing connected to it at all? The noise is probably caused by a bad capacitor.

"TVs are not user serviceable"

Not true. If it's still under warranty, I wouldn't think of opening it up but if the warranty has expired & you've got the skills, all you'd have to do is open it up & see if you can spot a leaking or swollen capacitor. They're not all that difficult to change out if you're handy with a soldering iron. Another possibility is swapping out the entire circuit board. If it's a common problem with your model, the boards shouldn't be too hard to find.

Does this buzzing sound come from the loudspeakers or inside the TV itself? There are all sorts of possible reasons for this symptom (including capacitors). An experienced TV engineer would probably get a clue from the type of buzz.

Always pop back and let us know the outcome - thanks

The "bussing sound" u hear may be normal because alot of LCD's make it especially when brightness is reduced. My samsung monitor make buzzing noise when brigthness is reduced.

Hi its a LA22A450C1 S . I googled and got the tech specs here http://www.samsung.com/sg/consumer/...
I use Linux(Ubuntustudio). I only use it as a monitor. Seems to progressively gotten worse over a long period of time. Seems the more windows i have open the more it makes the noise. I am not sure when i do things that requires more 'juice' like rendering video files(i also do video editing and sometimes audio editing). I havent done any editing for a few months.
Its long out of warranty but yes i know eactly what your talking about with capacitors. I have changed many in speakers many years ago. Thanks I was thinking that that could be the issue. I still have solder and a soldering iron plus i have a steady hand :0)

Thanks yes the buzzing is coming from the speakers. I think i pulled out the cable a few weeks ago and it was silent. Ah yes just tried it now and silent when the audio cable is pulled out. There is a fan sound (i think thats what it was) ofcourse.

Is this buzz absent when using the computer's own sound?

Make sure the connections are sound.

Also try turning the computer audio up quite high (software) and turn the monitor sound down instead (controls) - see if that makes any difference.

Always pop back and let us know the outcome - thanks

The computers own sound? Connections sound? Do u mean cables are ok? Yes cables are ok. Makes no difference the levels in the sound on the computer settings....up or down...buzzing still the same. Oh wait the buzzing is not there right now. Could it be when the computer has been on a period of time?

Is the computer sound level now higher than it was and with the TV turned down?

"Could it be when the computer has been on a period of time
All things are possible - give it a long go and see what happens.

Always pop back and let us know the outcome - thanks

I dont use this as a tv anymore. I think though it is related to what i am doing on the net. Maybe the amount of tabs i have open?

Thanks will try and pay attention to what happens but i am using the desktop less and less at the moment as too busy....thanks!
