I have a proscan 42LA45H 42 in television that has started making a buzzing noise from the back. What is causing this, and what do I need to do to fix.


Hi
If picture and sound is Ok, and only this buzzing sound is heard from the back of the TV, It should be due to core soose of some ferrite cored transformers inside, especially to the power supply regulator board of the TV. Open the back cover of the TV and swtich it ON. Listeen very carefully which transfromer makes the buzzing noise. Just trouch and press the core of the transformer suspected with some non-cunductive material like glass rod, or a stick of dry wood. You can identify the transformer that makes noise by this way. After identifying the exact transformer; switch OFF the set, unplug it from mains socket, apply some "Super Glue" like fast boanding glue to the joint of core of that transformer. Allow sometime for the glue to set. This will solve the buzzing sound problem of your TV. OK

Vizio GV42l buzzing


Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck

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.

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?
