Had Horz white line in center of tv replaced Horz output worked for two days. Also after replacing Horz out when turning on tv it would have black bars in upper and lower part of screen and a fuzzy white line in middle with a picture and sound. About 30 sec the picture would pop in and work fine lines gone and fuzz. Now it is back to Horz white line. I am thinking Yoke problem. Any other Ideas out there, and thanks
