NATIONAL PANASONIC TC42G
The basic problem with this set is lack of signals – just a
bluish -red raster with faint lines (pinkish) running across.
We’ve found a defective final i.f. transistor TR103
(2SA563A) and a faulty detector/a.g.c. i.c. (IC301,
AN231) to be responsible for loss of signals on this chassis.
Loss of luminance has been traced to the emitter -follower
