SOURCE: speaker buzz

Well yes your speaker is damaged, the cone actually has a tear, so audio that has low base or high pitch will cause distoration..

Simply remove it, take it with you and buy a similar one.. Same size, same watts, same ohms and just put the new one in.

speakers are standered only brand names are different..

BTW if you feel that you dont want to purchase a new one, simply stick the tear with duct tape, or you can hot glue it together.. If its plasctic, plastic weld works good(ask for it at a hardware)..

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Samsung P237HD tv/monitor,unit buzzing when on.


I would take it back unless you have time to investigate the problem before the return policy expires.

If the sound is coming from the speakers then it is interference and would likely happen with another TV.

The interference type can be electromagnetic or radio frequency, both of which can be defeated.
Start with plugging it into a different outlet. If that doesn't work, then unplug anything from it one device at a time to see which thing is the culprit. If it is one of the devices, move any audio cords away from power cords and/or position the device further from the television.
Household appliances and fluorescent lighting also can cause signal interference in electronics that is audible.
A device known to help with such interference are power line conditioners from such brands as Tripp lite, and ferrite clamps. You can place ferrite clamps on the power cords of your devices and their analog audio connectors.

This could be the speakers are vibrating onto the casing and need padding out more to prevent this.If this isnt the case, you may have a sticking coil on one of your speakers..When the sound distorts, remove one speaker in turn to see which one(s) are the offending unit(s) and replace. Is there a buzzing noise coming from the speakers especially in low volume? If so then you may have a faulty capacitor in your power supply producing hum on sound. Hope this helps :)

Quasar 1989 tv makes a buzzing motor sound


Hi and welcome to FixYa,

Initially, if you have confirmed that the source of the buzzing sound is from inside the TV, then that would indicate a component about to fail or would need attention. Let us try process of elimination:
  • tuner - most unlikely, the tuner is responsible for selecting the channel. No component/part of the tuner could make such a mechanical buzzing sound;
  • speaker(s) - most unlikely, the speaker could have a buzz but generally would not affect the video nor cause snow (weak TV signals);
  • transformer - a strong possibility although without knowing the exact model, at most generic ideas; power transformer, flyback transformer, horizontal drive transformer (unlikely);
  • arcing - another strong possibility. This could be caused by damp, dusty surroundings of the components especially at the FBT area. Another area that could have adverse effect when dusty/damp would be the anode cap.
This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Koss KLD2700 LCD TV no picture


http://www.fixya.com/support/t860220-screen_blank
As in almost all lcd type tv/monitor the backlight will go out and the inverter should be replaced at the same time. Your cost about 50.00 if you do it yourself.

Take care

Buzzing sound


You haven't specified where the buzzing sound is coming from, if it is coming from speakers, changing capacitors in the audio section will fix the problem, especially the filters. Now if it sounds like a hissing sound from back of the tv, the CRT base socket is the culprit. It is an easy thing to fix, and the base is cheap, but make sure you purchase the exact same type of base or it will harm the CRT. Good luck.

Weird noise over everything


According to the Samsung website: "The high pitched sound you hear is probably coming from the flyback transformer. The flyback transformer converts the relatively low voltage electricity that comes from the outlet in your home to the high voltage electricity needed to drive the cathode ray tube in your TV. It is not unusual for a flyback transformer to buzz softly when it operates. However, if the sound is loud and high pitched, it probably means the transformer is failing. To eliminate the sound, you will have to get your TV serviced."

Audio interference


Is the sound comming from the speakers on the TV or the back of it? Plasma TV's can doing buzzing sounds when moved to higher elevations.
