The old joke (and anyone who doesn't realise this is a joke probably shouldn't be inside a TV set) is : Tighten the yoke clamp until the CRT implodes and then back off quarter of a turn.

More seriously, many manufacturers (at least for monitors) put tape round the CRT neck under the clamp and the yoke tends to stick to it. I have never had the courage to force the yoke round after slackening the clamp. I remove the clamp totally (it's a bit like one of those 'jubilee' hose clips) then use a screwdrver in the slots in the yoke that the clamp goes over to free things. Put the clamp back very loose, turn the yoke as required and tightn to little more than finger tight.
