[Elecraft] K3 no transmitting

[Jorge Diez - CX6VM]

hello

My newer K3 is not TX anymore, on any mode, CW, SSB, FT8

The reception is OK, I can listen without problem, all buttons works OK, I
cal also decode in FT8

But when I want to transmit, no RF output, on any mode

I do TUNE and the display show two lines ( _ _ ) and 0 W

We used it in ARRLDX CW and it was working properly. Then I connected to
remoterig for the remote station, I think we did some QSOs with no
proble. other day I wanted to use it and noticed that it was not
transmitting

Any idea what could be wrong?

thanks in advance!!
