Re: Sony KDL-40s4100 No Picture/Sound/Backlight
Suddenly, my KDL-40S4100 developed the same problem. It was working fine one day, and not the next. No picture, no sound, no backlight - just the green power LED.
I checked for loose connections and found one or two, but the problem persists. I removed CN2502 and powered up. The backlight came on and the panel cycled green, blue, red, stripes. I powered down and reconnected CN2502, but the problem persists.
I have also checked for loose ground screws.
This is my first time trying to fix...
