Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

SOURCE: 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.

SOURCE: hi i have a Sony Bravia KDL37EX403U 37'' Freeview

This is a common problem with this screen, and is caused by a faulty inverter on the panel. Newer ones have a modified part and the fault is recognised by Sony as a manufacturing fault. Therefore you should have no problem having it repaired.

40 inch sony bravia making buzzing noises....any suggestions


Hello,
There are 2 small 1.5" fans that are located on the top right and left sides of the screen. These fans are of the non ball bearing type, so the bearings may be wearing out. You can either replace the fan or add a couple drops of oil to it. Remove the label on the back of the fan and put the oil there, it should quiet down. This will work for a while but eventually the fan will need to be replaced.
Good Luck!

Tv making loud buzzing noise


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.

Buzzing noise from TV when playing DVD/Photos


Usually this noise is the result of a bad cable. Unplug to see if noise goes away. If so, try different cables.Has solved that problem for me several times over the years.

It is most likely a fan (there are 2 to 3 of them in the set) that is making the noise. I doubt seriously that the lamp is causing a buzzing noise. The only other buzzing sound can come from the ballast wich powers the lamp.

Buzzing noise, sound but no picture


It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.
