i have a samsung HW-Q990F from a house clearence, it powers on, it works however the HDMI ARC port has broken pins, there are screws missing from the unit itself and the front speakers also there is no cover for it if someone was able to sort the issues out i imagine it would be a great sound bar, im not sure but the audio sounds distorted but i am not sure there is visible signs of wear on the unit itself aswell please inspect the pictures closely there is also a slight tear on the right side speaker so this is being sold as seen batteries not included with remote power lead is included i dont accept returns as i have stated it needs repairing
