Hi everyone, (my first post on forum)
I'm having difficulties with my NAS unite Zyxel NAS542 and looking for schematics or service manual ( the NAS540 it's the same unite just a small diffrence in color).
Brand: Zyxel
Model: NAS542
PCB https://www.easyzoom.com/imageaccess/d81dfb29aba242efb1cba5e34d263323
Symptom: the device is shorted, I think it's near the input 19V (left, down corner of PCB).
any of your advice will be appreciated.
tnx
