Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth NO POWER Error Fix: Soundbar Will Not Power On

Error code NO POWER on the Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth means: Soundbar Will Not Power On. Soundbar shows no signs of life — no LED indicators, no display, no response to remote or buttons. Check: (1) power cable is firmly connected at both ends (wall outlet and soundbar), (2) try a different wall outlet — verify with another device, (3) check if a surge protector tripped — try plugging directly into wall, (4) inspect power cable for damage, (5) perform a power drain: unplug for 2 minutes, press and hold the power button on the soundbar for 15 seconds with it unplugged, then plug back in. If still no power: internal power supply has failed — most common cause is a blown fuse or failed capacitor on the power supply board. Requires service or replacement.
