I have tried using a Verizon-supplied remote IR extender in this standard definition STB but it does not appear to be operating properly.
My understanding is that when this device is plugged in to the rear panel of the unit, the front panel IR sensor gets disabled and only the IR extender is operational. However in my particular case, the front IR sensor is NOT disabled, and the rear mounted IR extender itself does not receive signals. I have tried (1) rebooting the STB several times, (2) using the online and STB repair applications, and (3) replacing the Verizon IR extender with several other cables that I know are operational. So far, no luck.
First, is the front IR sensor SUPPOSED to become disabled as I described, and second, does it appear that the IR extender function on this particular box is faulty?
