Power Supply is no voltage at the output, even purple +5 volt cable. In the Primary section, I'm looking for a defective item. We test fuse and diode bridge by Ohmmeter. Fuse is open and short circuit diode bridge. First MOSFET separate circuit would result from the check this out of the circuit when the transistor Q101 is determined to be defective item. The defective fuse replaced; Another test Power Supply do not short circuit. Power Supply is ready.
