Herelink receiver problem

Hello! . Today I flew with HereLink and in flight I lost control of the control panel. When the Quad returned in RTL mode and landed, I saw that the receiver was not working and the control lamps did not light on it.
for power I used BEC 12V 5A
Now he does not react in any way to any connection.
Where and How can I order a new receiver to replace?
