Razer Blackwidow Chroma v1 death

Hello everyone, since a few hours ago my Razer Blackwidow Chroma keyboard stopped working simply by disconnecting it and reconnecting it.
I have tried everything, change port, change PC, the same thing is happening; Razer Synapse (v2) recognizes it and shows it to me, in fact I can activate the "Game Mode" from there and the LED indicator on the keyboard turns on, but if I change the lighting it does not update. No keys work, no block num, or functions with FN.
The lights turn on, and they do weird things .. It had a previous effect to disconnect it, and it shows and overlaps with the classic wave of a lifetime.
I tried the FN for 5 seconds, and the keyboard shows no sign of life.
The device manager detects it as "Razer Blackwidow Chroma."
I tried reinstalling the Synapse and it did not work either.
Unfortunately, Razer's warranty does not cover my country, and because of customs policies it is impossible to send it.
Of course, thanks for the help, and sorry for my English ..

 

Is the keybord have the same behawior on difrent pc ?

 

Exactly, in three computers with Windows the same thing happens (One Notebook windows 7 and two desktop computers with Windows 10)

 

I think this is a hardwere issue mayby with pcb if you the same thing on difrent devices. In this point it will be best to send keybord to shop where you buy keybord they will handle your warranty.

 

Unfortunately it is better for me to throw it away than to take it as a guarantee, the shipping and customs costs are exaggerated. (and it would be convenient for me to buy a new one, considering that it is expensive because of the value of the dollar)
Is there any way to erase the last settings that were made? Install a new firmware? I want to try everything before using it as a paperweight. Thank you!

 

Ohh ok but i can say you this if razer warranty is not in your country but you buy keybord from local store or store it's in your country the warranty transfer to this seler.
