Question about Samsung SCX-5115 Fax Machines

1 Answer

No Power - DOA

Samsung SCX-5115 MFP - No power. Fuses and Diodes test "good", but I don't have the Service manual, so don't know what pins should have which voltage. I see a couple of "burnt spots" on the board, but the resistors in those areas test with the correct resistance and the associated Diodes are also reading good (with no load). Should I just replace the powersupply, and hope for the best, or what are the test points I should use to verify first. .. Thanks; Mike

If there are burn spots on the power board, then it is shot. Go to to get a manual, most likely they'll have one there. I service all makes and models of printers, faxes and copiers, they usually have what I am looking for.
