Very int. Field collapse, white line in the center of screen for a few seconds, and then black screen with no sound.
When the problem occurs, make continuity check between pin 12 of the yoke plug and pin6 of vertical IC. If open, fit a piece of wire.

Won't start, goes to Stby. Hor driver T541 Sced, supply resistor R503 oc. After replacement, It was Sced again.
Change C546 0,33uF/250V located in front of the LOPT transistor. Also check/replace C503 22uF cap.
