A customer recently came in with a Yamaha P115 that would not power on. The customer claimed the instrument hadn’t worked since a lightning strike near her house.
This one was a pretty easy diagnosis. The main DM board is the primary picture for this post!
Additionally, the volume slider and several of the buttons were damaged. It’s unclear whether this is a consequence of only a lightning strike, or if there was also a spill involved, but either way, the damage is impressive!
