Try adjusting cables connecting dvd to tv. If this doesn't work try a different cable.

My GPX tv/dvd combo is making an intermitent 'buzzing' sound,anyone know how to fix it?


Is the sound coming from the speakers? (do you hear it with the sound turned off)

Either an audio problem if heard only with sound up or if a buzz with sound off it is a coil or transformer on the circuit board vibrating hard enough to produce the noise.

Both are fixable but require different tactics to resolve.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv


Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

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.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.

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?
