Diagnostics: This board will not solve the'no backlight' problem, unless your power supply is turning on but not supplying the LED voltage to panel. Some of these models have a problem with tv cycling on and off. That can be either the power supply or the main board. If power supply is not supplying 5 volts to main, then power supply is bad.On some models you can confirm a bad main by disconnecting it from the power supply and if the tv powers on with backlight then that means bad main. No video can be either bad main or t-con, but more likely to be t-con. The item "BN44-00503A UN55ES6150 UN50ES6150 UN55ES6100 UN55ES6003 Samsung Power Supply" is in sale since Monday, April 2, 2018.
