picture darkened, turned it off for a min now it won’t turn back on

@alan11 when you say darkened do you mean darkened or do you mean turned black. This sounds like a power board issue but we would need to get more information from you. Let us know exactly what it is that your TV does. If you have no sign of life on it then you want to remove the back from your TV and arm yourself with a multimeter. First unplug the power board from the mainboard and see if your TV’s backlight comes on. You can see that by looking at the back of the panel through the vent holes etc. Check the power going to your board and then measure the voltages to your main board. It will help if you [post some good pictures of your boards etc. with your question. that way we can see what you see and hopefully help you out a bit better.
