The three things I asked are voltages and signals that can give some idea of conditions of the boards. The backlights coming on and staying on with that particular connector unplugged may or may not be applicable to your model. I haven't been able to locate sets Service literature. Many late model Samsung TVs have that feature to quickly give a go/no go as to backlight conditions.

The only indication the set is not dead is the power light lighting (& ticking/buzzing). You DO have control over the on/off indicator, both turning on & turning off? With Remote control as well?
OFF = STB. Is the pin labeled "A13V" 13 volts? According to pictures of the boards on Shop Jimmy, the Power Board has a wire/TP labeled "STB: 8V / ON 13V", Is that behaving as labeled? Is "Power ON/OFF" correctly toggling, from a very low voltage to a higher voltage as you turn it On & Off?
