Topic: Clicky black keys

[NAMA]

Some month ago I bought a secondhand PSR-SX700. Is is a very nice keyboard but now have the problem of the clicky black keys as discribed in previous posts. There is no warranty on the instrument. I have a technical background so it should not be a problem to do the repair myself. In the previous posts I cannot find what the best grease is and I like to receive some advise on this, like suggestions on brand, typenumber, where to buy etc. I also like to receive more detailed information about the procedure to replace the grease. I welcome any information. Thanks in advance,
Greetings from The Netherlands.

Hello Nama,

Here is Yamaha's recommendation sheet on this problem but I can't find it in France.
Personally I would go for Lithium grease which is white in color and perfectly suited for plastic.
A small drop as stated on the Yamaha spec, should be enough to resolve this rattling.

Have a good day

Don't use lithium grase. Use synthetic PTFE grase.
