Please help Roland XP-80 middle keys no sound

I 've just had a Roland XP-80 from a friend, everything works fine but there are some middle keys not sound when i press them. I need advice from somebody who know how to fix or where i can bring it to be fixed... Thank you for reading this topic and any advice

Most of the time, you just have to clean electrical contacts beneath the keys. This thread shows how I did it with my own keyboard a while ago:

Fixing dead keys

Hi

I m Ignatius from India, there is a swith pad of rubber material inside your keyboad body. You just have to clean those key pad. Most probabely by cleaning those pad your keys are going to work. if you are not able to do it your self pls contact service center.
