does am insignia 55" lcd flat screen and TV have any power supply fuses? if so what do they look like.

Solution
Fuses are pretty rare in TVs these days. If there are any they would look like a glass cylinder with metal caps at the ends. There is a wire that goes from one cap to the other. When the fuse is blown the wire is burned out. Here is a pic:

If you search for the Make model number and service manual you might find it.
