HP Laserjet 4M- 67 Service

Hi:

I have a Laserjet 4M that displays 67 Service after startup. Service manual states replace the formatter PCA board. Did so with board out of another 4M which is working and received same error code. What's the next step? Have a spare for parts, so can cannabalize if need be..

THANKS in advance!
Bud
