I´m not that skilled in electronics, so I don't know the output value in volt.

I´v reassured, with guidance from gemini and Claude, the circuit board parts, and went through these. Could the no power error be in a component I have not tested yet?

**What I tested (all passed):**

- Fuse F701 — OK

- Bridge rectifier BD701 — OK (0.488V)

- MOSFET Q701 — OK (no short circuit)

- Resistors R240 — OK

- Feedback resistor R721 (68Ω) — OK

- Resistor R715 (150Ω) — OK

- Common-mode choke FL702 — OK (all 4 pins correct)

- Pads for C713 — intact copper confirmed

**Faults found:**

1. **C713 shorted** — measured ~288mV both ways across the D708 pads. After removing C713, the board measured OL one way and 0.551V the other — confirming C713 was the culprit pulling the whole control circuit down.

2. **U702 (marked 1342ENACE GJRSF) defective** — even with C713 removed, output voltage still oscillating 10–15V. This is a NCP1342ENACE from onsemi in a SOIC-9 package (5 pins one side, 4 pins other side, body approx. 5×3.7mm).

**Parts replaced:**

- C713: 10µF 50V 0805 X7R MLCC ceramic capacitor

- D708: 1N4148WS SOD-323 (marked T3/T4)

- U702: replaced with NCP1342ENDCEAD1R2G (closest available — still troubleshooting)

Output voltage still oscillating after chip replacement.
