Okay, sounded as if you might have been ordering it from a site. Seems like you know what to look for. The image that is displayed looks fairly nice for alignment, although there is no pattern on the upper edges and left/right sides to look for, everything else does look very in line. Knocking a tube about is never a good thing, shadow masks or Trinitron wires can get dislodged if impacts are really tough, and obviously you don't want the glass to get scratched or for the thing to get dropped. The typical ailment of a widescreen CRT with some use or age is drooping sides that curve downwards. Service menu items do things like convergence, colour setting, moire controls, and rotation or tilt, seldom will the above problem be tackled directly or first by a menu setting. This is either a problem of deflection, of deformation of the shadow mask, or with beam alignment which may or may not be related to the two, and sometimes this can only be fixed with physical placement of small magnet-like strips along the tube surface. It's something you can do yourself, but which takes a real knack to do well, possibly a fair bit of luck, because if you overcompensate you can cause other problems, either with colour or geometry. Power does weird things when not converted properly. Hiccups are common with converters of all kinds, certainly much safer to just use the native 240 when you are in that area.
