Question about Sony BRAVIA KDL-40V2500 40 in. LCD HDTV
All the time my sony 40w5500 bravia is on I can hear a buzzing/fizzing type of noise from the back top right hand corner. Not very loud. This maybe quite normal? Can anyone put my mind at rest? The TV works perfectly.
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.
