el.pedro7I have tried to restart in that way. But no chance, no screen nor vibration
Did you hold the power and volume down button in for a good 5-10 seconds? I have also experienced what seems to be the same thing. The phone's display at certain times stops working, and will not turn on but I know that the phone itself still operates as I can feel haptic feedback on the display even though I can't see anything. A soft reset using the two buttons always restarts the phone and then it's fine until the next time. Wonder if you have the same issue?
LP_ASUSYup seem like no choice but to send it to the service center.
I'm sorry to hear that. As a last resort, you can try another cable to see if it might be a cable failure.
But most likely, this is some kind of hardware failure and you will need to contact an ASUS service center for a warranty repair.
