@marcmsk since there is an image created the T-con board is unlikely. Leaves you with either the power board or the LED backlight strips. Post some good pictures of your boards so we can see what you see and hopefully "show" you where to check the power board. The other thing you can do is try and get an LED backlight tester ($USD20 on Amazon/Walmart etc). That way you know for sure. (Gut instinct, it's a Philips and you have an image=backlight array;-)
