First time user! Tried posting yesterday but hadn't left a whole lot of information. I was watching my set over the weekend and heard an audible sound from the back of my set. My picture and menus are completely gone, however sound remains. I did a continuity test on the only ceramic fuse I could find in the entire set and the fuse was functioning properly. Based off the walk through on this board the most logical fault would be the y-sustain, or y-main card as Samsung refers to it. It's my understanding that the majority of y-sus cards have their own fuse, and based on my research the last couple of days I haven't encountered any instances of so few fuses. Obviously a repair is more affordable than a new set, but money is tight and before I order a card i'd like to be certain that it is a y-sus problem, and that fuses are a non-issue! I've attached a picture of the entire set, as well as the y-main and power cards. Any help would be greatly appreciated! It may also be of note that earlier in the day a single horizontal line appeared in the middle of the set, which went away after several minutes!
