We are here to help! If you're unsure of how to diagnose and troubleshoot the TV message or call us for more assistance before purchasing! We offer FREE PROFESSIONAL TECH SUPPORT. The only real way to properly troubleshoot / diagnose is by trial and error since there could be several boards that show similar symptoms and possibly more than 1 board not working. Sometimes the symptoms change. Be patient with questions from us and exchanges!

Product review & video

okay here we have this 39 inch LED TV it's an insignia and as you can see we've got it plugged in you see the red light is on and we're going to power it up get the power light puts a few times and the picture and/or backlight should come up by now as you pursue this actually nothing so the first thing that I always do is just double check is a nice bright flashlight put it up against the screen as you can see I do see some words there and then that time go ahead and hit the menu button make it very obvious for you and as you can see you can definitely see the menu on the screen so we either have a backlight a bad LED backlight problem or well we're back like probably the way it goes but they need to be caused by that LED inside of the screen here or it can be caused by the main board not telling not sending the backlight on or LED on signal to the power supply to shut on the LED circui
