Hi, I've been using a Eurovox in Dublin for the past 5/6 months on n*l. Works perfectly, well... almost perfectly. Every now and again (sometime every 5 min, sometimes every 5 hours) the image will flicker and knock off for a few seconds. It gets annoying after a while. I'm wondering if this is normal? Is there any way to prevent it? Also, any ideas on what might be causing it? I'm thinking it might be down to a fault in the box itself.
