I try to find a replacement for part L5A3 : 321Z005A20 (made by "kd") that
seem to be faulty in IIYAMA monitor
(primary shows 0.3 ohms, must be 1.5 to 2.5 with my evaluation of internal
resistance)
Search on the web give only one result ( www.smelectronic.com) for
321Z005A10 (without secondary).

Is there any equivalent part somewhere ?

Thanks
