Easy way to check your power board:

disconnect the cable between the power board and the mainboard. plug your TV into a wall, if the backlight turns on then your power board is good. if it doesn't you either have a power board or a backlight issue. 

 Tip to fix your TV:

power cycling, backlight turning on and off, lines on the screen or no picture on this model is because of bad screen, replacing power board does not solve these issues, It is not in our policy to do a full refund on items returned in opened, used, or damaged condition in that case Fees may apply to our boards in case of return. we will send you a board in 100% working condition. feel free to get back to us with any question about your repair.
