Sorry, most of us do not have the psychic powers to solve your problem. Give us more information and we may be able to come to a solution. See 'black magic'.

It may be a PBL3717 (I think that is the number). Search for anything that has something to do with stepper motor drive and has the same package. Try st.com. Sketch the connections to the ic - the power and output pins should give you enough info to match.

If it is a ULN2003 all the inputs are on the left hand side and the outputs on the right hand side. Check pins 8 (gnd) and 9(diode com).
