You have a vert sweep colapse. Fisrt thing is to get a schematic diagram and find the vert. output Ic and the clamper diode. Measure the voltage on both sides. If its low then its apossibility that the Ic was drawing loads of current and blew out the b+ feed resistor. Look on the schematic and trace back the voltage line from the vert output ic back to the sweep power supply on the secondary of the flyback transformer. check the limiter resistor to the feed and if its open replace the cap right there the resistor as well as the vertical output Ic ALL AT ONCE!!! If you dont you will cause it to go out again in a short time. Good Luck.. If you post the vert part of the schematic I will be more then happy to assist you with this repair.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

No Picture On Screen and red line in middle.

The set has a vertical problem if the line you mention is from side to side ,if the line is from top to bottom the problem is in the horizontal circuit and both can be repairable,a vertical fairlure is a common problem,the vertical IC goes bad and it takes a safety resistor with him to prevent any more damage,the horizontal is rare but it happens too,if you are familiar with tv service you can change the IC but you will need a service manual to identify the part,you can get a manual overnight if you downloaded it at www.servicemanuals.net,if you are not too familiar you should seek the help of a servicer for safety reasons.Let Us know how it goes or if you need more information.
