Turn the brightness all the way down (if that extinguishes the line turn it back up until the line is visible again but dim) until you fix the vertical.
Even weak tubes can produce a bright line, you will know it is a good tube once you fix the vertical.
Tubes can be an issue, but bad capacitors, and resistors are a more common cause of vertical deflection failure....I hope the vertical output transformer and yoke are good, they are not the most common cause of that type of failure, but still a possible cause, and often hard to get replacements for in many sets.

I just updated this thread and I stated that it was due to a bad Vertical Output/Vertical Amp tube, also I didn't leave that set on for very long only for a few seconds to get the picture and to test it and that's it, I immediately turned it off afterwards. Do you honestly think I'm stupid enough to not know about Picture tube burn in?
