sharp LC50LB481U The TV originally led would flash and not turn on but I did a factory reset and now it turns and has an image if a flashlight is shone at the screen. I’m trying to figure out if it is the backlight array or the backlight inverter is there a way to test and see if it is one or the other. the parts to repair both are pretty expensive and don’t want to have to buy both if only one is broken
