Hello,

I have a X5D with a problem where 3 keys in sequence work and the next 3 don't; it goes like this across entire keybed. Tried swapping cables and the problem remains, it's the same with cables swapped, so it makes me think the problem is on the mainboard.

Any ideas?

Thank you all.

I believe those keys are rubber membrane contacts. They are probably dirty or worn out.

You have to take apart the keybed, and clean them with alcohol. If that fails to fix it, the next step is to use a repair gel called "CaiKote" on every single contact, and that restores the contact's ability to be conductive again.
