SOURCE: Vizio makes loud static noise, picture goes fuzzy.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

I notice that some of my cell phone wall chargers make a high pitched ringing sound, not that loud though. I think cheaper internal electrical components are the culprit. (Opinion)

TV making loud buzzing sound


More sets than you might imagine have this kind of problem---I a regular TV it is usually a transformer that is vibrating hard enough to make the sound---the higher pitched sound is just that--a sound.

If this is a direct view(means not a flatscreen and has a Glass Picture tube it will be either the high voltage transformer or one of several smaller transformers.

This can usually be fixed---seen a few so loud the cats in the house run away.

Let me know model number of set for more information.

On chance it has the high voltage transformer I attach a photo of what that looks like.

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Rca 27410tyx1 will not shut off


Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

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."

You need to change the Audio / Control Head, as well as the Pinch Roller of the machine. A worn out Audio cum Control Head will reflect in poor tracking and so will cause the above problems.
