Sensor light turns off when TV turns off

Hi, I have a UN32M4500BFXZA TV, and when the tv is turned on from the button on the button, the sensor light in the bottom right corner goes off and the remote does not work. I tried a different Samsung remote and it doesn’t register on this TV.

I am pretty sure that the IR sensor is toast, but I figured I would check here to see if there’s a work around, if there are any Bluetooth remotes that would connect and control without the IR sensor, or how much an IR sensor replacement would be.
