TV Problem

[DG]

the three colors of my TV are not on top of each other,

there is a vertical gradient where the middle is perfect but at the top and
bottom the colors are really off (not on top of each other),

horizontally there is no gradient,

there is also a noise(vibration which is oscillating at specific rate unless
it is at the moment a channel is being changed) coming from the yoke (not
too sure if its from the yoke I didn't want to bring my ear too close)

was wondering whether this would be a tube, yoke, turner, v/h synch, power
supply and etc problem,

and what type of faulty component I should be looking for: capacitor,
resistor and the like

Thanks,

Dero

Sounds like a loose trimming magnet in the yoke. Never saw a Hitachi do that,
but Philips had problems with it for years.
