As I mentioned, Jeffrey, the remote is working. I have an I.R. tester, which confirmed that there is an o/p whichever of it's msny buttons is pressed, but the Pioneer Receiver doesn't respond to any commands from the remcon, even though it is otherwise fully operational. I can check the IR receiver from the Pioneer on my 'scope or by substitution with a new GP1U277X IR receiver, but I'm beginning to suspect that the fault is elsewhere in the circuit.
