now i am very desperate!! I opened the switch but now i don't know how remount!!!
Ok i found T503...must i checked voltage on each pin with scope?1. Find component T503 on the schematic and the PCB layout.
2. Notice on the schematic that T503 has two supply inputs (marked as +IN and -IN).
3. Stick your oscilloscope probe on each of these points in turn.
4. Measure the voltage rail ripple.
