Help in Identifying the IR sensor point
A good method to identify the IR sensor point which may not always be obvious on AV equipment such as AMPS, it to use a book or similar. Place this in front of the equipment with the remote control facing it, so that the book blocks out the IR signal and the remote stops working.
The next step is to simply move the book slowly without moving the remote. At the point that the remote starts to function, this is the point where the IR sensor is located on the equipment.
Below is an example of where to find the IR sensor point on SKY boxes:
