AR7200BX Won't bind...

I had some problems with my AR7200BX, which I have figured out. However after searching the web, the solution I found myself was nowhere so I am posting here in case anyone else has the issue. On Sunday, my AR7200BX initialized fine for the first flight. The second flight it took a couple of tries to connect but eventually did so. The third flight, it took 4 or 5 tries but did finally connect. For the fourth flight, it would not connect. I tried rebinding, even unplugging everything and powering it from a 4.8V battery pack and using a bind plug. It would not work. I was very unhappy as this is not an inexpensive unit. I opened it up and found 2 PCB's, one which is obviously the BeastX controller and the other looks like the PCB in a DSMX satellite receiver. Their are 3 posts that connect the 2 PCB's togethor, obviously VSS, VDD and signal. I tested back from each of the traces to those connections on both boards and found one to be broken. I grabbed my soldering iron and re-soldered the three connections between the 2 PCB's. Now everything works great, it binds over and over with no issue. To be safe since this is a compromised unit I am also now using a satellite DSMX pod just to be safe. The unfortunate thing is the AR7200BX built in receiver must be working for the satellite to work at all...

Anyways, very happy I saved myself $300 for a new AR7200BX...

I hope this helps someone else with an AR7200BX problem in the future...

If the unit is under warranty, I would strongly recommend sending it back to Horizon, my unit is 2.5 years old so warranting it was not an option.

If it isnt under warranty I strongly suggest sending it to Horizon. They will fix it free of charge. You pay shipping!
