Re: Sony KV1320UB shadow on screen
I'm not sure what you mean by compositor. Suggesting a tube fault tells me you don't have too much experience with TV sets, so all cautions about high tension, high vacuum and lack of mains separation apply. The most likely culprit is the smoothing electrolytic for the supply to the cathode drivers.

Compositor is most likely an un-noticed autocorrect error. Capacitor probably was the intended word.

Are you able to post a good picture of the symptom?
