Congratulations to have found the cause. If signal level on P3 screen becomes unstable while the BNC cable is completely plugged in at both sides, check the cable itself. My case was that the signal level was unstable and sometimes went very low. I had thought that K3 or P3 circuit was in trouble but found that connection inside one end of BNC cable connector was unstable. Replacing the cable completely fix the problem.
