Bruce, direct views have not had dynamic convergance since the days of the
old dleta tubes(guns arranged in a delta formation), Usually there will be a
stipe of paint on magnets,seeif these has been disturbed, whole magnet
assembly may have moved,or if it is not bonded yoke may have shifted, I once
had a sanyo in for another problem and had to completely reconverge,even
though it had never been touched, hth.
