Hi,

if the LED is always on, perhaps comment out the lines that turn it on
and see if it is then always off.

At least this way you will be sure the PIC is running and something is
executing.  If that works then it must be timing.

If it doesnt then the PIC may not be wired up right, bypass caps ?, mclr?

Oh, and what joy when I got my first LED to blink.
