the problem is in the verticle section, if you are a technician check a verticle IC and a capacitor of that stage. to allocate a verticle stage follow 4 cables coming down from deflection coils, two of these wires goes near transformer, this is horizotal and the other two goes near an IC this is verticle. positive idea.
