i have recently bought a loewe aconda (black & lovely). fantastic picture, except slight horizontal/downward bowing of picture. not normally noticable unless showing widesreen in 16:1 with black top & bottom or there is long horizontal line on sreen. deflection of about 3 mm across width of screen. question is: is it worth me getting an engineer in to sort it? doesn't seem to be anything in the service menu.
