Unhappy Blade CX2 - Tx and RX won't "sync" up

Blade CX2 with separate 3-n-1 and receiver.
E-Flite LP5DSM 2.4GHz
Fresh batteries in both.

Ah, flying an indoor heli outside in a 5mph wind, the pain, the pain...after I finally found it, I now experience the following:

Fresh batteries in both TX and Heli.
Power ON TX with throttle and trim all the way down.
Plugged battery into heli.
3-n-1 LED flashes red 3 times then alternately blinks red and green. Receiver LED does not light.

Bind plug installed.
Plugged battery into heli.
Receiver fashes rapidly orange, 3-n-1 flashes red 3 times, then red and green alternately.
Same light pattern, they do not turn on solid. (did not bind).

Could my TX be bad as opposed to the heli?
The fact that the lights came on at all with the bind plug installed leads me to suspect the TX.

I think that maybe the easiest thing to do , would be going to a local good hobby shop, thy should be willing to help out, maybe trying to bind your heli to their trans. then you will know for sure.

But I am also sure there are many on this forum that have the same equip. and can help also.

If xmit was working fine before mishap, odds are it is a problem with receiver. What does manual say about light patterns on rec?

Yes, I finally tried another TX and had same problem. Manual merely shows how things should respond when all goes well, including bind procedure. I even took everything apart: no magic smoke seems to have escaped any of the chips, etc. If I remember correctly (which I probably don't) it looks like the same kind of light pattern that happens when I forget to turn my TX on before the RX (oops, would I ever do that?).

Default Regarding DIY Electronics Repair in RC

But, I would like to attempt to REPAIR damaged gear before replacing. I am an electronics enthusiast and actually enjoy a little downtime if I can repair it myself. Call me a masochist or maybe just a man in penury.

Thank y'all VERY MUCH, I enjoy this new RC hobbie (so far), heh.
