Going by your description it appears that a "High" on the port pin drives the LED ON. Well I am just guessing that you are NOT using any buffer between the port pin and the LED.
If it is so, then first modify the LED connections so that they come ON when the port pin goes "LOW". Some LEDS remaining always ON can also mean a partially cooked MCU - poor fellow trying to source current beyond its capacity must have given up the ghost... Raghu |
