Hello Everyone. I have a Roland XP-50 with an issue, where the LCD display window lights up with orange background but no text. It's a great keyboard and I want to repair it so that it's usable again. Last time I took it to Sam Ash, they tried to charge me $350 to replace a $3 battery. I live in South Florida. Does anyone know a place I can take it to or ship it to for reliable and reasonable repair ? Thanks.
