Does that set have the xxl tubes? I had a problem with those when I first powered up the 42-400. (Dirty contacts) Jiggle them around and wait 10 seconds or so. Also, my reception would go out occasionally , but found if I rocked the 7a4 tube, reception would come back in after about 10-15 seconds. Found that underneath on one of the connectors, it was loose in the housing, making intermittent contact with the pin. Made a wedge (out of a round toothpick) and super glued it in. Hasn't lost reception since.
