Members pbone Posted October 16, 2012 Members Share Posted October 16, 2012 I have a line on a P50m piano module that the seller says that it's flashing an Er1 message, which does not affect anything on the thing but the storage of presets. Not a huge issue but I'd like to fix it anyways. So, Yamaha's tech people here in Seattle are going to charge me $95 at least to fix this thing. I don't have a soldering iron but may be able to procure one. I know how to solder too. Can this be a DIY job or will I {censored}ing fry this thing?
