Sorry this is giving you problems. The fact that the display goes out is troubling, indicative of a power problem maybe. Only thing I can recommend is powering up the pedal while pressing the top left Hotknob button. This boots up the pedal in UPDATE mode. Connect the pedal via USB to a computer. Use the Eventide Device Manager to see if it detects the pedal. If so, reinstall the latest version of the firmware. Once that is complete, I would conduct a factory reset by holding down the big encoder and the right footswitch while powering up. Keep in mind this erases all presets and system settings, so I hope you have a backup. Let us know if this does not work.
