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!

@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. Agregar imágenes a una pregunta existente

Make sure you have a multimeter so we can check a few things

Hi @jazzbo ,

Since you get the splash screen and the unit stays powered on, I'm wondering if it is a software problem rather than a hardware problem. Which would also be on the mainboard where the problem may be as suggested by @oldturkey03

Here's a link showing how to update the firmware in your model TV.

I don't know if it will work if your TV's firmware is a later version or not.

You can contemplate attempting this as a last resort if all else fails to resolve the problem
