hi

i would be grateful for any help again if possible, i have just had the tube replaced in my avant (rf dvd version) by b&o and apparently the original tube was a revision 1 which is no longer available and has therefore been superseeded and replaced with a revision 2, which also includes some new circuitry and a software update.

the tube was replaced yesterday and everything appeared to be fine, however after watching it for a while it appeared that when watching some things there was a problem which can only be described like a problem you may have if there the pincushion correction wasn't setup correctly, i.e lines that should be straight near the edges of the screen (e.g. a picture of a door frame) appear to be curved at both top and bottom.  the strange thing is it doesn't happen on everything, i.e. if i watch standard terrestrial tv the problem doesn't appear to be apparent, whereas if i watch the same channel through the sky+ (which is set to 16:9 ratio) then the problem is apparent. also, if i watch something like sky news (which i think may be broadcast in widescreen) then problem isn't apparent but if i watch a dvd like toy story then it is ??, all of which  has left me a little confused!

i'm about to go back to b&o about it now, but thought i would post the question here first in case any light can be shed on what the problem might be

thanks in advance
