You said white line in center, of this is down the middle then it's a line scan, usually scan correction components or dry joints a possibility...
... if its across the middle then it's the frame/vertical scan problem, this could also be dry joints or a faulty vertical output drive chip.
Leaving it on with a bright line will burn the inside screen coating and cause permanent damage, better to keep this at a low brightness to avoid tube damage.
