I need to replace IR LED diode in TV remote control.
The only thing I know is that is 5 mm in diameter, is there something else I need to watch out before I buy new one?

I already checked it with a multimeter, it's not flashing, it's dead.
I need to unsolder and solder a new one, I just need to know what is right part.

Forgive me then we should get right to the point if you could possibly provide me the make and model of your television. You know what my mistake I didn't realize I had my crystal ball. That was supposed to be a joke I'm trying to lighten the mood.:rolleyes:
