Samsung TV 2016, 49 - no power, no red light, blinking backlight
It sounds like you may have a couple of issues, it's normal for the backlights to come on if the main is unhooked but the flashing sounds like bad lamps. The 5 volts is standby voltage, next step is measure the PS_On pin when you turn the set on and see if you get around 3 volts there, if you don't you have a main board issue.
