Yes, I have had the transmitter for about a year, it has worked flawlessly. I have an x18 also and use ethos suite for all my upgrading. I've been using my x20 pro a lot lately, a couple of days ago I went out to fly but when I went to turn it on I had no screen or light, just dead. When I plug it in to usb the charge light comes on momentarily because the battery is fully charged, also tried different battery. It is definitely bricked. I'm starting to think I have a hardware failure, would be my first one and I'v been flying frsky stuff since vers 1 X9D Taranis was out.
