SELBSTJUSTIERTE BILDROEHRE

A pair of locating washers (34, 36) are applied over the holes (84, 86) in the bottom mounting lugs (24, 26) of the kinescope (20). The washers (34, 36) have apertures (44, 46) which are precisely referenced with respect to the position of the kinescope screen (38) such as by using oppositely-disposed locating marks (104, 106) on the screen (38). The TV cabinet (22), on the other hand, is equipped with a pair of tapered guiding posts (74, 76) on the inside front surfaces (70, 72) thereof, which are similarly referenced relative to the rectangular opening (78) of the cabinet (22). When the kinescope (20) is mounted in the cabinet (22), the cabinet guiding posts (76, 78) are received into the kinescope-mounted locating washers (34, 36) to assure registration between the kinescope screen (38) and the cabinet opening (78). The kinescope (20) is fixedly secured to the cabinet (22) by a plurality of screws (64).
