Raspberry Pi IR blaster — transmitter IR LED won’t light, everything else checks out

Building an IR blaster on a Raspberry Pi Zero 2 W to control my AC. The receiver I can read my Carrier remote and capture codes fine. The transmitter won’t emit any IR.

What I’ve already confirmed:
• ir-ctl -f -d /dev/lirc0 reports the device can send raw IR (carrier, duty cycle, etc.)
• Sending runs with no error: ir-ctl -d /dev/lirc0 --send=power.txt
• The capture file is valid (full +/- pulse data)
• Checked the IR LED on a phone front camera — no flicker at all
• Swapped in a fresh IR LED — still nothing
• Transistor pinout confirmed C/B/E, emitter is grounded
So software + Pi side seem fine; I think it’s something in the breadboard wiring I can’t spot. Photo attached. What am I missing?

I made this tool for college and school

Hi, i have been working on this side app for a few months now . It has event reminders , schedule management, profiles , file upload , to do list , and more.
It’s 100% free forever and secure.
Unfortunately im unable to publish it on App Store bec i don’t have the budget for a developer account but maybe soon ill do it.

Give it a try and lmk what u think of suggestions, issues , anything. Thanks
