This tv have a colors wheel. The tv colors wheel is dead.The buzzing noise is the cause of the colors wheel is spinning of is axis and rubbing sides of the motor.Hire a tv tech. for the job.Colors wheel is hard to replaced,because have to take out many other machanical parts,even before can change the colors wheel it self.
Something has shorted in the set causing the power supply to make that buzzing sound. Most likely the short is in the horizontal circuit. The horizontal makes the high voltage work which in turn lights the picture tube.
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.
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.
The sound is a result of the faulty CRT base, and you will have to replace the base socket. Make sure you by the exact same type of base, and if you are not a techie, get a qualified technician, this is not a costly problem.
