Replace Transfer Belt Kit and re-seat connections on PRCB and HV unit. Swap magenta PH with cyan PH to see if problem follows.

are you checked the position of your lasers after having changed them?

Did you take all the lasers out to replace the magenta or just the one ? I'd check your ribbons you might not sat them all the way in or caught them on your way out.

Horrible job I've only ever managed to replace one without taking them all out and do it from right to left cuts my hands to bits every time.

Its one of the flat cables not seated correctly, seen it a few times. Don't forget to check the flat cable on the board next to the yellow iu, sometimes this gets pulled without you knowing it while your fafing around trying to get one of the lazers out.

Possible that the PH was not proper sit. Do check the connection of PH.
