SOURCE: I got a sony bravia tv (model#KDL-40S4100 serial#1030160)The screens black but sound works. I see the menu with a flashlight. I changed inverter boards but it didnt help. What could/should I do next?
Have you measured if the inverter boards are getting power from the power supply?
Since you've replaced the inverter boards and still no backlight then there is a defective CCFL tube. This type of repair is a bit more difficult because of where these lights are located.
