A week ago tomorrow we had a lighting storm. I have the M4 on its own circuit and of course plugged into a nice surge protector. However, I have a LAN cable from my wireless router into the piano. Lightning actually cut the telephone line (my DSL) and it got my AC, outdoor spa, PS3, many other items, and of course, the M4. I am not aware of a surge protector from the wireless router to the piano. Does anyone have ideas so this doesn't happen again?
I live in Kentucky and Tom Kaplan from St. Louis has ordered the gambit of boxes and will be down when they arrive. 1-800- ProYamaha was very helpful and sent me to Tom. I've only had the M4 for 14 months and this has been aweful (I even lost the engine to my light airplane the night before this happened - had to do an emergency landing at a friend's grass strip - new engine ordered now). Bottom line - I need surge protection from the telephone wire too.
Guys - enjoy your piano this day. I hope I'm back with you soon. This repair could cost $1,500 to $10,000. I've never ever experienced anything so mean as this lightning (and we lost power in January for a week due to an icestorm). Listen to some Chopin for me :) and protect the internet connection to your machine!
