I’ve had my V2 Ktuner for a few months now and before today it has been fine. I plugged my unit into my desktop and it would not connect to the software and the screen was flickering. Now the unit will not power on when connected to the computer at all, no LED lights or screen on. The same goes for when I plug it into my car. The unit appears to be completely unresponsive and does not power on. What are your suggestions on the fix? Any help would be greatly appreciated.
