Turnigy 9X HELP NEEDED!!!

[entomophile]

I have used 4.8v power from NiMH batteries, 6.4 volts from a LiPo, and 5v from a regulated dc power supply. I have also tried multiple servos. I think the RX is fried. I can't even get it to bind anymore. I had no problem binding FrSky modules on the same radio, and the same servos ran fine on that RX. I opened up the original RX and TX modules and they are UGLY! Obviously hand soldered surface components. I think I just got a dud.
