I received my new chip, plugged it in and everything was great. I decided to put the unit in a more permanent housing, turned it on, nothing. I noted I had my +5V and G connection reversed to the receiver. I have checked evertying else and it appears to be correct. What are the chances I have destroyed the IR receiver? Is there something else I can check? I have checked wiring continuity and voltages, everything appears to be correct, the unit will not turn on.
