We have a FET driving the IR led. Along with a current limiting resistor. These are not shown in the diagram.
Not much point in posting a schematic if it is not correct.

We've scoped pin 3. It shows a 30khz square wave. We've scoped pin 9. It shows serial data being transmitted.
And what about pin 8? Anything detectable happening there?
