[Dead] Duplo DF-920 folder won't power up

Checked the 24v from power supply it is there, replaced the main unit (main PWB) still not coming on.

Problem fixed - ended up being the main unit, operation board, main motor, and tray size sensor. The problem was caused when the customer removed a plate inside the machine to clean the rollers and when installing it (wrong) it pinched the rollers causing the motor to bind and take out the boards he also lubed the origional side guides and oil dripped down onto the size board also bent the guide in such a way that one of the sensors was broke. (customers gotta love em)

Glad to hear you figured it out- sounds like an expensive fix...
