Narrative:

A B737-800 departed lax south complex on laxx departure procedure. A B737-700 departed north complex on loop departure procedure. The -800 checked on at shoreline. As the -700 was checking on; I noticed that the -800 was still on what appeared to be the 250 departure heading; not the required 220 heading at the smo 160R to separate this aircraft from the north complex which is on a 250 heading. As soon as the -700 stopped its transmission; I issued a southbound turn to the -800 to effect separation. I am probably going to start issuing all of these non-RNAV departure an initial heading as soon as I talk to them. This situation of the pilot not turning to the required heading is happening very often and I'm not sure; but I think that 'fusion' makes it a little harder to discern when this turn is started. Aircraft are not turning when they are supposed to and so the controller needs to correct the situation.

Title: SCT Controller described a developing conflict with LAX departures when one aircraft failed to turn as required; the reporter listing 'Fusion' RADAR as one contributing factor.
