Tv service part 2

DEFECT: Single Vertical Line In The Center POSSIBLE HINTS : 1.) Check first the vertical IC. Some Vertical IC’s may have loose contacts on solder joints on its legs because of the heat and cold condition on its operation. 2.) Check the supply voltage if present in the main vertical section, sometimes 24 volts from the flyback and other supplied by 24v and -24v plus ground. 3.) If the supply voltage is missing, check the line from flyback having 18-24 volts, possible culprit is an open fusible resistor. 4.) Defective yoke, maybe there is a broken or burn part of the coil inside it. 4.) If the supply voltage is present, possible problem is that the Vertical IC is defective or the Vertical Sync coming from the Jungle IC, better to check also the jungle IC in this situation.
