I am working on repairing a 19k7000 that showed no picture when I got it and had no neck glow. The HOT was bad. After replacing the HOT I could only get it to turn on by lifting D10. I replaced IC4 with one that is known good and now it will turn on with D10 in place, but the B+ is around 160v DC and there is only a horizontal line across the screen about 2 inches thick. When I turn it off, for the split second that it shuts down there is full deflection but is in vertical collapse otherwise. The chassis has been re-capped. I have looked over it for broken traces and cold solder. Any suggestions on how to proceed would be great. Thank you.
