RCA hdtv sound but no picture

sounds more like a vertical problem since the audio still works. If it were multiple green lines then I would say green tube but the tube will usually shut a set down and it will be dead no audio. Try replacing the audio output IC

No picture on tv screen

try resoldering the vertical output IC. sounds like the cRTs are blanking due to the vertical. If that doesnt help you may need a new IC. While youre there look for signs of the CRt leaking as often it leaks right onto the vertical output section real close to the IC.

Great picture no sound

Youre audio output IC is probaly defective. Try replacing the IC its only a few dollars and thats usually the problem with that chassis when audio drops out completely.
