@dixielatino you did not tell us if the power LED stays on when your screen turns off. Check in a darkened room with a flashlight angled against the screen to see if it is your backlight that turns off. When the display gets dark, shine the flashlight angles against the screen. See if you can still make out shapes. Let us know what you have checked so far. Pull the back off to take a look at all the boards. Check for leaking or domed looking capacitors. Post images of what you see with your question. That will allow us to see what you see. Use this guide for that. Right now it sounds like the power board/inverter is turning on and off due to either bad capacitors or bad IC’s. More information will be necessary
