    medyo bro hehehe, bitaw kasagaran symptoms ana kay inig plug nimo moblink ra ang power LED nga blue or usahay wa gyud hehehe, pero mabaw-an nako nga naay consumption kay mo spark man ang plug inig tuslok nako sa 220V, naa say standby power nga 0.13 amps sa AC clamp meter

    Nice observation bro, mo spark na because of the main capacitor sa primary sa PSU.

    mao gyud sir hehehe, naay 280+ volts DC sa primary pero di ka oscillate ang ferrite chopper (high frequency Transformer 20 KHZ+ kapin) kay di na man straight DC ang feedback voltage sa secondary mao na mabuang ang opto isolator kay ripple na man ang voltahe, off freq. na mao na mo stall ang oscillation resulting nga mo blink ra,
