A friend of mine gave me this phillips47pfl7432d/37 tv. He said the left half of the screen was totally dark and if I wanted it I could have it. I pulled the back off, and on both the master and slave inverter boards were Samsung 680mfd 35v caps with the ends split open. I replaced the caps and this is how it works now. Left side is still darker than right but watchable. (its better than it looks in the video). My question is how can I tell if the problem is in the master or slave board, or is it something else causing problem?

Thanks ,
I gave that a try, and could get no change, I also tapped on the sides and edge and could see no change. http://www.audiokarma.org/forums/images/smilies/headscratch.gifAnything else I could test, or has it likely seen better days.
