Please report what You found. These things are all very important you must ensure the equipment is not receiving an IR signal from two different sources. If operation is still not good, you can try moving the flasher away from the component a little bit to reduce the amount of IR light that the component receives. The last thing to try is removing the antenna from the MRF-250 to see if that helps.
