Many things. Any open or short in the wiring to the grid, or possibly a bad ground, or a bad switch or fuse. More than likely, though, is that the grid is split somewhere, Id look there first.

If the top 3 lines work only then you have a break somewhere. Trace the lines and see where it breaks. They do make some stuff to fix it.
