Door Video Intercom

Hi I have a very old 49-7203 door intercom which is intermittent in its operation.Picture & or sound does not always come on when the monitor button is pressed or the picture does come on but flickers & collapses.I think this is some sort of power supply fault? I have changed most of the Electrolytics to no effect.Any ideas would be greatly appreciated.This is one of 2 units in use;the other one is still ok. Thanks Malcolm
