Following a vertical line that appeared on the screen of my cockpit xs9 transmitter, after putting it to charge and also later today I put it to charge the battery and 2 more lines have appeared. I have decided to reset the transmitter for this reason and when starting it again it goes to the screen calibration configuration and the calibration logo of the controls. In this configuration of the calibration of the controls it shows the error ES261. So I can no longer advance in the configuration and the transmitter. So at this moment the transmitter is blocked and useless and there is no way to get out of here. The lines on the screen have not disappeared. In addition, this calibration error of the controls had already appeared since I bought the transmitter, it appeared when trying to calibrate the controls without resetting the transmitter, I did not give it importance because the transmitter worked well, but now I think that I should have used the product warranty. Does anyone know how to solve this problem?
