Help me. transmitter error.

[tmfla1]

Hi. my name is LEE.

I have x8+ and used it during 6 months.

One day my drone got a failed and sometime transmitter's display had been error.

After error I checked transmitter, pixhawk, etc.
I guess it's reason of error would be pixhawk and d4r-2 telemetry so I purchased new its.

But now I listen only beep sound by transmitter when I was turn on it.

Please help me. I already send e-mail to 3dr robotics but they don't send me reply until now.
