What is this component in a RCA tv?

[Sealtest]

Found an odd component that I need to know what it is. No matter what the component will not read with a multimeter so I am guessing it is one of those ceramic low ohm resistors that serve as a fuse. It seems that this part is blocking current from making its way to the ground.

Any info would be great on this. I would really like to get this tv going.
