I had a Sony HTCT550W and returned it. When hooked up to the sharp TV via ARC (HDMI input #1 on sharp TV) the sound bar would turn on & off when the TV was turned on and off, but the problem with this Sony soundbar was that the default input setting was the digital input/output connection. Every time the TV was turned on I had to change the input selection to ARC /HDMI #1 to get sound from the sound bar. A call to Sony and they confirmed unfortunately the soundbar would not default to the ARC connection when powering on.
