Narrative:
Aircraft #1 departed dca and did not establish communications with appropriate ATC sector until 7 mi northeast of airport. Target of aircraft #1 was incorrectly displayed on the radar screen: its data block was assigned to another sector; and that sector's data blocks were inhibited. By the time the situation was recognized; aircraft #1 came in close proximity of aircraft #2.
