Now open frame power supply and I will check the secondary section with  Ohmmeter. If the test capacitors on both sides of the ohmmeter needle move, capacitor or diode should be replaced. Open Capacitor from circuit with, and Ohmmeter check again and I determined that the diode is healthy or not. The Power supply the eye becomes apparent that some of the capacitors broken.
