Audio information then feeds into the limiter, ratio detector, audio amp etc... Video goes to the CRT cathode through a 0.05uf cap that has been replaced with a new 0.047 uf cap. I've only been looking at the video route after pin 5. Should I still go looking backwards?
Well yes it’s said that video rides along audio so you can still go backwards but at this point there could be a problem with the alignment coils and still have sound but no audio. Try different channels 3 or 2 or maybe 6 I had one of these sets that had sound but no video blank screen and it was a think ts 4h with the adjusting coils in front so I concentrated on channel 3 and eventually got video. Remember you probably don’t know the history of the set who know who was in it or what may be bad in the IF section.
