The panel or TCON board has failed, the solution is the same replace the panel. Not worth the cost, get a new TV

SOURCE: I have a Sony Bravia KDL-46Z4100 46' I have a green vertical line

this is probly the lcd control module unfortunatley it comes with a new lcd panel
change these.

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.

Testimonial: "Thank you very much for the very prompt reply. This seems a very likely cause. My TV is only a week old so I will contact the supplier. Thanks again."

This also happened to me and may continue to get worse... If it goes away for a while after warming up, then it is the same problem... The LCD panel is probably going out, when that happens the cost to repair it is more than the tv is worth... If it is in warranty then you can have it replaced or fixed.

Testimonial: "You were so right. Thanks."

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...
