Joel,

The 'zero-ohm' resistors are just pieces of wire used for purposes that
double-sided PCBs are used for. Apparently cheaper to insert jumper wires than
to make a double-sided board... The only failure mode you will see is that the
deflection or HV board will not work properly. If you don't replace the jumpers
with new wire, you are only asking for trouble.
