Shimano Steps system display fails to turn bike on.. Contacts and wiring are all good... Switched with another display from another easy flow and bike turns on normally. After vigorously shaking and tapping display after removed from its cradle, it worked again, then failed the next time we stopped.. Back to tapping and shaking, no joy.. Finally took the display and threw it in the air about 20' landing on soft grass. It tumbled on the ground. Put it back in it's cradle and it has worked since.. Anyone else have this issue?
