Hello, I live in Chile. Thanks for your wellcoming. My Kawai K4 is dead, mainboard failed. I checked and I change the IC from the main supply-the VCC regulator-The 9VCC are good now, but no sounds and no info in display, although appear some strange signs repeated at the display, the inner light is on. I need to replace the mainboard. I would buy a K4 in good condition. I want the whole thing without the keys and the basement, I need all the things attached with screws to the base. Anyone who wish sell me that items, please, write me to: email@example.com
; or a letter to: Buin 1154, LIMACHE, CHILE. Thanks for all!
