Strange keyboard Error

Upgrade

Hi

Working on a 820-3115 MB, Came in with faulty keyboard , middle row keys not working only, ie. ASDFGHJKL, assumed faulty keyboard and swapped

New replacement keyboard has except same problem all keys workign except middle row letters

Tested with additional keyboard and exact same fault

Looking at connector and it seems OK

Compared all pins on connector with known working board in Diode mode and all close readings

New to this and not sure what or how to test next

Any help would be great
