SOURCE: Loud buzzing

check your connections again, if you have the audio and video reversed you will get this exact problem no video/ fuzzy video, and squealy noise out of only one speaker (other will likely sound correct) You're watching the sound channel, and listening to the video channel basically... hehe

The main cause off buzzing from these sets is the transformers on the psu. This can be solved by sealing the transformers with a sealant spray.

SOURCE: Polaroid flm-373b lcd tv - making a loud buzzing

Possible that the main power supply unit which is the SMPS- switch mode power supply- has a faulty capacitor or in the INVERTOR board which has changed the value and so the frequency being changed can cause higher huming level- reduced to lower frequency.
so check the board for leaks , if so replace. Also check if the threshold voltages are below level in these circuits. if so the capacitor can be identified. If there is change after the component heats then simulate the circuit board and confirm using a hair dryer.

A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

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.

Buzzing/fizzing noise from back of sony flat screen tv


Below is an image of rear side of your TV, Sony KDL-40W5500
Top right corner is marked there and possible cause of noise seems back light inverter board, there are high voltage going to CCFL inside LCD panel and seems high voltage leakage causing that buzzing/ fuzzing noise.

Replace back light inverter board upon voltage leakage confirmation.
Thanks.

A piercing high pitched buzzing noise when on. The sound volumne does not affect the buzzing. Always very loud.


You didn't post a model number but if this is a CRT TV (non-flat screen) the noise may be coming from the high voltage circuit and may be a warning sign of failure in the near future.
