Hi guys ive got a really weird problem with my openbox s11. Basically it wont connect with my 50" Plasma, it used to work fine before and then for the past few days it would flicker and now it wont connect at all. Ive tried different HDMI cables and the problem is still there. The weird issue is that the problem only occurs on my 50 Plasma TV, the box works perfectly fine on my other 19" and 32" inch TV. I know the HD Port on my Plasma is not damaged because the Sky HD box works fine. Also noticed when im in the openbox menu the picture is fine but as soon as i go into a channel picture starts flickering and then i get a black screen? Any help would be appreciated guys?
