Hi, I’m new to this group, apologies if this question has been answered before. I’ve have a Beovison Horizon for the last couple of years and it’s been excellent, but recently the terrestrial TV picture is very intermittent and generally just drops out; we’ve been mainly using streaming apps to watch tv. The aerial in the house is shared to other TVs and they’re all working fine, so I guess there’s an issue with the Horizon electronics? Happy to open up and have a look and replace parts, but hoping for a bit of guidance.   Thanks in advance Rob
