Hello,
I use a Kronos LS 88. The problem started with velocity issues on these keys, then they stopped working or sounded very weak and stucked.... This is sure a connection or PCB issue.

But last 10 days, the problem disappeared ! That's nice but I want to be sure it won't come back. Which PCB should I replace to fix it definitively ??

Thanks a lot.

Hi

Usually that kind of odd behaviour (notes usually in Thirds not working) means problems with the Key Contact Board (the pcb that is below the Keys itself) it could be as easy as cleaning it with alcohol, in the worst case scenario, maybe a new one will do the trick.
