Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer INIT Error Fix: Soundbar Initializing / Resetting

Error code INIT on the Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer means: Soundbar Initializing / Resetting. The soundbar front display shows "INIT" — the unit is initializing or performing a factory reset. During normal power-on, "INIT" appears briefly then switches to the selected input mode. If "INIT" appears and the soundbar does not proceed past it, the unit may be stuck in a reset loop. Causes: firmware corruption, button stuck during power-on, or failed factory reset. Unplug the soundbar for 60 seconds, then plug back in. If stuck in INIT loop, try a manual factory reset: power on, then press and hold the Play/Pause button on the remote for 5+ seconds until "INIT" appears. If the loop continues after factory reset, firmware may need to be reflashed via USB (download from samsung.com/support).
