C128 repair help wanted

I have a C128 PCB assy 310379 Rev 7, which I am trying to repair.

The symptoms are:
When the following are pressed on the keyboard, it does the following with certain keys

7 nothing happens
8 moves left
Y nothing
U scnclr
G moves down/return key
H nothing
V run
B monitor

The other keys work properly

I have swapped U1 CIA 6526A with a good 6526A

Also I have also tested it with 64 Doctor cartridge, for the joystick test:
With Port 2 it showed Right (joystick pin 4) as being pressed, when there was no joystick attached.

Does anybody have any ideas on how to fix this.
