⚡ Easy DIY Troubleshooting & Common Fixes

🔧
Power supply does not turn on or no LEDs light up.
prob_01
Common root cause: No power from the outlet, AC cable improperly connected, or internal fuse blown.
Step-by-step solution: 1. Check if the outlet is working with another appliance and if the AC cable is firmly connected to the power supply and the outlet. 2. If the problem persists, the internal fuse may be blown, indicating a need for technical assistance.
💡 Pro tip: Always use outlets in good condition and avoid low-quality extension cords.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How to verify if the power supply is delivering the correct 12V? cfg_01
Use a multimeter set to DC Volts (V=) and measure the voltage at the power supply's output terminals (usually marked with + and -) while it is powered on and under load. The reading should be close to 12V (common tolerance is +/- 0.5V).

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty should be claimed if the power supply fails to function without apparent cause after correct use, such as not turning on, emitting a burning smell without overload or short circuit, or if the output voltage is consistently unstable and outside tolerance, even with adequate load and correct ventilation, indicating a potential manufacturing defect.
