.4v, normal operating conditions.
no video is not "normal operating conditions", so until there is normal operation of the RF-IF to video input, and the AGC feedback loop is normal, the .4v will always be abnormal.
The sound det is taken from the plate 3rd If, via C43, if V7 is not in the right state, it can clamp down on it.
