Hep: Flashing Red LED

[NazaNovice]

I have a Flame Wheel 450 with Naza controller and DX6i transmitter. When I power on, the ESCs arm, but then the LED on the FW450 flashes red and nothing else happens.

What I've done:
1. I replaced what appeared to be a bad ESC. The FW450 worked for a short time after the repair, but then it quit.
2. The Assistant delivered an error message saying the transmitter was out of center range (or something like that). I sent the transmitter to Horizon Hobby, which replaced gimbals and the antenna.
3. I still got the error message, but error message stopped appearing after I reprogrammed and calibrated the transmitter. However, the red flashing LED continued, and the FW450 won't run.
4. The transmitter worked fine with a quadcopter at my local hobby store (which unfortunately knows nothing about DJI/Naza). So I assume the problem is with the Naza, other components on the FW450, or connections on the FW450, not the transmitter.
5. I found and fixed a broken solder on the new ESC.
6. I replaced the new ESC in case I had damaged it.
7. I pulled and reinstalled all wiring to ensure nothing was loose, upside down, or in the wrong place.

The ESCs still arm and the LED blinks green for a couple of seconds, but then it goes to blinking red. This happens whether the transmitter is turned on or not.

Does anyone have any ideas or troubleshooting tips? I would greatly appreciate any help.

As the manual states the sticks are not at center. This can be caused by trim, or sub trim. I don't program in acro mode so know nothing about end points, but would think this could also make the Naza think it was off center. When it states sticks not at center, that does not necessarily mean that the sticks are physically off center. I have had that error myself, and it was simply that the trim was not center.
