This solution is for no keypad w610 or k550i...
1. check and clean conector keypad to board
2. measure the continuity of the tracks
3. replace board keypad
4. check switch closed (key volume, play, stop etc)

but if not none of that

replace chip db20xx internal esd proteccion "MARIKA_SECURITY_EFUSE"
100% solution!!!

luck to all!!!:)
