Question about LG 42PX5D 42 in. Plasma HDTV
Check the fuse on the y-sustain board it is probably open circuit. I suspect the zapping sound is one of the IC's on the buffer board has blown (this would cause the Y-sustain fuse to blow) this is the board on the left hand edge that is connected to the Y-sustain board, there is more than one & if you inspect them closely you will probably see one that has cracked, if this is the case then replace this board. Then replace the Y-sus fuse.
