No picture, no sound, no blinking lights on Sony KDL-40W600B
Cannot turn on with remote or button on TV. Unplugged power brick, waited overnight. Applied power again. Got a brief Sony logo on screen, then it went dark. I have repeated the power disconnect/reconnect several times. Results always the same. No picture (other than the Sony splash screen), no sound and no blinking lights of any kind. I notice that after the splash screen the display has a very dark purple-ish tint until I remove power. Is this a bad board? Any help with which one, if that is the problem? Thanks in advance!
ANSWERS:
"@jazzbo ""this “after the splash screen the display has a very dark purple-ish tint “ is most likely your backlight being on. This could very well be a mainboard issue. Post some pictures of your boards with your question so we can see what you see. Adding images to an existing question
Make sure you have a multimeter so we can check a few things"
It sounds like you have a faulty LD BOARD. Replace it you are good to go. just for emphasis it is the second picture you uploaded.
