My R3 is completely dead..

[KWANGTOK_CHANG]

Hi,

I have used my FSSB R3 since 2013 (S/N: 0048).
Today I noticed Y axis was not responding and stuck to the center.
I started RS tool and verified that Y axis is not working.
So, I removed the usb connector and reconnect it.
And then, R3 is not recognized at all.
What do I need to do?
Do I need to send this for repair? If I have to how much does it cost?
I am very sad and depressed..ㅠㅠ
