hello~
I have a limeSDR, I use it carefully, but it keeps having problems. After I removed all the antenna cables，I can’t pass the Lime SDR TestAPP when starting up.
There are problems with clock network test, LMS7002 Test, and RF loopback loop.

After the PCB is powered on for a period of time, the board becomes hot and sometimes works. If the PCB is cooled by a fan, the board will die again.
It looks like there is a problem with the circuit manufacturing soldering.
Requesting RMA
