Re: LG 50PK950-TA Plasma TV with Audio - But no Video

I have a 50PK450 LG plasma with just sound. I replaced the upper buffer after discovering that screen (bottom half) would come on when the top buffer was disconnects (had another lg plasma that had the same exact symptoms and replacing the top buffer only fixed it). I was wondering if I can now get away with now just replacing the y-sus and not harming the new buffer. I have replaced all 3 in the past (minus the other lg recently) and would not want to go in circles killing boards.
