Maxwell Posted May 22, 2019 Share Posted May 22, 2019 I've inherited a PX-830BP everything works with the exception of 20keys all scattered but a cluster of them around middle C area. I started to remove the keys but wondering if it wouldn't be better to remove them all and clean them off including the circuit board and rubber boots. I noticed the white grease, is that lithium grease used on the keys and in case the rubber boots need to be replaced (I hope not) but would these still be available from Casio?
