Folk just want to warn you that fixing TVs can be a shocking experience!
Do as little as possible with any power connected, apply lots of common sense and always with one hand in your pocket and you will survive.
The scan coils are around the neck of the tube up against the flare. They can with care be rotated slightly to straighten the picture. They may be secured with a clamp of some sort. Do not force anything, wear safety glasses when working near TV tubes.
Try a tiny rotation with the set disconnected from the mains, then see if it is better.
Beware, high voltages can and do persist long after the set is off. A good rubber glove is a good idea. One hand only remember.
