I am having problesm with my Samsung DLP(HLN617W) where originally I had to replace my Lamp. Now 6 months later, I have to replace my ballast, but while doing this, I believe that I may have blue a fuse on my power board. In an attempt to remove the power board, I am having difficulty. I have removed the analog board and the power board appears that all I have to do is slide the power board out, but it is not working.
