Hi guys. I recently bought a T8-S and every now and then, it seems to lose the connection to my TV. It mostly happens while I am waiting on a movie or TV show to start streaming or while I am navigating through the lists or menus with the remote. The screen just goes blank with a message saying no connection. It's as if the box switches itself off, even though the blue power light is still on. I then press the standby button on the remote and it returns to the main home screen. I've made sure the HDMI cable is secure on the TV and the box. Any thoughts on this issue ? Thanks
