IR blaster not working



It's for my galaxy note 4 (910A, att version)
Recently, my daughter dropped note 4 on very hard surface (cracked the screen) and had slight water damage. So camera failed also.
So I have replaced the LCD and rear camera. Camera still didn't work, but after I unseated all the cable and seated again, then camera works. Pretty difficult experience.

But today when I checked, I found IR blaster doesn't work. IR LED works, but on mirror or camera, when I clicked the IR button (PEEL smart remote), there is no light coming out from a hole beside the headphone jack. So I am guessing, hardware failure.

To replace this, what part should I buy? It seems to me that this part is connected to proximity sensor and front camera. So I am looking at the eBay item like this: Replacement-Front-Camera-Proximity-Sensor-Flex-Cable-for-Samsung-Galaxy-Note-4

Sorry I can't post the link for this.

The seller doesn't respond whether this fix also IR blaster. Does any one know?

Could someone recommend the trouble shooting guide for IR blaster? *#0*# doesn't really test the IR blaster, just test IR LED. Am I looking at the right location for IR?
