Quoted from guido:Hi Davi, I appreciate your help.
Shouldn't I check J123, pins 4-5 according to the image you have uploaded?
What I don't understand yet is what solenoids 27 and 28 are and where I locate them. If they are defective, should I replace them?
At 1st step, makes sense to check voltage levels.
As 2nd step, check the traces at bottom side, from J123 pin 4-5 to the sub-circuit around Q20 and Q22.
