Question about Sony STR-DN1030 7.2-Ch. Wi-Fi Network A/V Receiver
Not sure if my kids did something, but unit does now power on. Power light changes when plugged in from red (dot) to green for a few seconds then clicks off. No other lights come on. I opened the case to find the fuse next to incoming power is blown 8A 125V. I replaced the fuse to find it immediately blows the new fuse. Nothing odd with incoming power 110v (standard) and unit does not have a incoming power switch to alternate.
Look in the circuit board area where the power cord mates with it for capacitors that have bulging tops (instead of the flat tops that are normal). If you see even one, you need to replace all the large capacitors othe power supply section (normally around 5 or 6).

Testimonial: "Without removing any boards to inspect closer, I don't see any capacitors bulging. I will pull boards and look closer later tonight. I unplugged the transformer from all outbound connections and powered the unit ON... No blown fuse this time... Power cord goes into a small sister board (with fuse) and then to the transformer."
