I bought the Sony A8G and htx9000f soundbar around 8 months ago and has been working fine. I've recently unplugged the hdmi, which i have done before, but this time when i reconnected the hdmi cable it says there is no connection and to make sure the devices are on. If you unplug the cable it says nothing and the screen is just blank. I believe something maybe loose inside the hdmi port, has anyone had this issue with either of these?
