My V6 box has for some time been playing normally on for instance Netflix or occasionally a tv channel, and then the tv/sound will flicker on and off endlessly until the box is switched off completely and restarted. I get no error codes or any other information, and 90% of the time it works perfectly. The video attached shows what happens. I'm reluctant to get an engineer out for something that doesnt happen regularly.
Thank you for reaching back out to us in our community, doing a reboot will not lose anything on the box, all you need to do is unplug from the power socket, leave 2 Minutes then plug back in.
