Since you have very good sound, and this set uses intercarrier sound, it seems like the video IF has to be working on some level, and the video amp. That doesn't leave very many components that could be giving a problem. Check the wiring and components around the video amp stage and the route for the signal from that stage to the CRT cathode. Make sure the coils on L14 and L15 (in SAMS) are not open. Is the brightness control working properly? Does the contrast control have any effect?
Also, have you adjusted the fine tuning oscillator coil slug in the tuner for the channel you are using?
